1.1 kW Electric Motor Price and Sale

When you need a compact electric motor, one of the most sought-after ratings is the 1.1 kW electric motor. Found in pumps, fans, small conveyors, packaging machines and countless general-purpose applications, this power class runs reliably for years when selected correctly. On this page we have gathered everything you need to know about 1.1 kW electric motor price and sales: pole/speed options, frame size, efficiency class and mounting types, all in plain language. As HEM Motor, our goal is to help you source the exact motor for your need quickly from stock and buy it with a clear price-performance balance. For stock availability and a fast quote on electric motor prices, you are in the right place.

Why Is the 1.1 kW Electric Motor So Widely Preferred?

1.1 kW, roughly equivalent to 1.5 horsepower, is considered the backbone power rating for small and medium machines. Booster sets, small centrifugal pumps, blowers, dosing systems, packaging lines and laboratory setups frequently use motors at this rating. With low power consumption, a lightweight body and easy installation, it is preferred both in new machine builds and as a direct replacement for a failed motor. Because stock availability is high in this class, lead times are short and the price balance is favourable.

Choosing a motor correctly does not end with the power figure. Speed (pole count), mounting type, body material and efficiency class directly determine how well the motor fits the machine and its running cost. We cover each of these below.

Pole and Speed Options: 2, 4 and 6 Pole

The 1.1 kW motor is offered in three core speed options. The rotation speed your application needs determines the correct pole count:

• 2 pole (approx. 2800-3000 rpm): Ideal for centrifugal pumps, small blowers and high-speed benches.
• 4 pole (approx. 1400-1500 rpm): The most preferred, most balanced speed step. Most conveyors, mixers and general-purpose applications run at this speed.
• 6 pole (approx. 900-1000 rpm): Suited to low-speed applications requiring higher torque and calmer operation.

If you are unsure which speed suits you, simply share the rpm value on your machine nameplate. Our power and speed options guide explains the pole-speed relationship with examples.

Frame Size, IE3/IE4 Efficiency and Mounting Types

The 1.1 kW motor is usually built in frame 80. This standard IEC frame size guarantees a one-to-one fit of shaft diameter, foot hole spacing and flange dimensions with the machine. If you are replacing an existing motor, sharing the frame number and mounting code with us is enough for error-free supply.

IE3 and IE4 Efficiency Class

Today, energy efficiency regulations require motors to meet certain efficiency classes. For 1.1 kW motors, IE3 (Premium) and IE4 (Super Premium) options are offered. An IE4 motor runs with lower energy loss and reduces running cost in continuously operating applications. For intermittent or short-duration use, IE3 is often sufficient and more economical. When deciding between the two classes, daily running hours should be considered.

To explore the difference between efficiency classes in depth, the articles in our IE3 electric motors and IE4 electric motors categories will guide you. In the product range you can review IE3 efficient electric motors and standard electric motors options.

B3, B5 and B14 Mounting Types

How the motor is mounted to the machine determines the mounting type:

• B3 (foot-mounted): Classic floor/base mounting. The most common choice for conveyors, fans and general machinery.
• B5 (large flange): Used for applications connected directly by flange to pumps and reducers.
• B14 (small face flange): Preferred in small pumps and machines requiring compact mounting.

Determining the mounting type correctly is critical for the motor to fit the machine exactly. For mounting options, our B3 foot-mounted electric motors and B5 flange electric motors pages provide detailed information.

Single-Phase or Three-Phase? Choosing the Right Supply

The 1.1 kW power class is a critical rating available in both single-phase (220V) and three-phase (380/400V) options. If your facility has a three-phase grid, a three-phase motor offers higher efficiency and lower starting current, which is why it is preferred in industrial applications. Where only single-phase (domestic 220V) supply exists, a single-phase motor is a practical solution. We can determine together which supply type suits you by looking at your existing electrical infrastructure.

Factors That Determine the 1.1 kW Electric Motor Price

Looking only at the power figure when checking price can be misleading. The same 1.1 kW motor sits at different price-performance points depending on the chosen features. The main factors affecting price are:

• Efficiency class: IE4 contains higher material and labour content than IE3, so the price-performance balance differs.
• Pole/speed: Some speed steps are more abundant in stock, affecting supply speed and balance.
• Body material: A cast-iron body offers heavier duty and longer life than aluminium.
• Mounting type: The choice of B3, B5 or B14 changes with mounting needs.
• Stock status: Sales from stock mean short lead time and favourable price-performance.

For a clear fast quote, simply tell us the pole, mounting and efficiency class you need. As HEM Motor, we offer the most suitable solution with the advantage of sales from stock.

This means your machine starts running quickly rather than waiting. Whether you are replacing a failed motor or building a new machine, we can identify the right motor the same day and start the supply process quickly. You can also get information about our sales and dealers options.

Typical Application Areas of the 1.1 kW Motor

The reason this power class is so widespread is that it suits a very broad range of applications. The most frequent use areas we encounter in the field are:

• Booster sets and small water pumps: Widely preferred for building water pressure, garden irrigation and small transfer lines.
• Blower and fan systems: Used as a small fan motor in workshop ventilation, dust extraction and flue aspiration.
• Packaging machines: Provides precise, low-vibration operation in filling, labelling and winding units.
• Mixer and agitator units: Ideal for mixing drive in small food, chemical and cosmetics production lines.
• Conveyors and transport belts: Used with low-speed 4 or 6 pole motors in short transport systems.
• Reducer drive: A B5/B14 flange 1.1 kW motor connects directly to worm and helical reducers.

If your application is not on this list, do not worry; we determine the right speed and mounting type together based on how your machine runs. For conveyor applications our conveyor belt electric motors, and for pump applications our pump electric motors pages collect suitable options.

What to Consider When Replacing an Existing Motor?

When replacing a failed or worn-out 1.1 kW motor, a few pieces of information are enough for the new motor to fit the machine exactly. Sharing the following values from the old motor nameplate is the fastest path to error-free replacement:

• Power (kW) and speed (rpm): 1.1 kW and the speed value that determines the pole count.
• Frame number: Usually 80; defines the mechanical dimension group.
• Mounting code (IM): B3, B5 or B14; shows how the motor is mounted.
• Supply voltage: Indicates whether it is single-phase 220V or three-phase 380/400V.
• Efficiency class: Clarifies your IE3 or IE4 preference.

With this information, we can identify the replacement motor the same day and share the stock status. If you wonder when buying new makes more sense than rewinding, the guide articles in our electric motors category offer a comparative view.

Body Material: Aluminium or Cast Iron?

At small powers like 1.1 kW, the body material is also part of the choice. An aluminium body is light, easy to handle and install, and ideal for clean, light-duty environments. A cast-iron body is heavier but superior in vibration damping, mechanical strength and long life; it is preferred in dusty, harsh or continuously operating environments. We can evaluate together which material is right for you based on your operating environment. For cast-iron body options, take a look at our cast-iron body electric motors page.

Frequently Asked Questions

How many horsepower does 1.1 kW correspond to?

1.1 kW corresponds to approximately 1.5 HP. Therefore users searching for a 1.5 HP motor usually reach the correct product with a 1.1 kW motor.

What does frame size 80 mean?

Frame 80 is the mechanical dimension group of the motor in the IEC standard. Shaft diameter, foot hole spacing and flange dimensions are standardised to this frame, so motors of the same frame are interchangeable.

Is a single-phase 1.1 kW motor as efficient as three-phase?

Three-phase motors generally offer higher efficiency and more balanced starting. If you have a three-phase grid, choosing three-phase is more advantageous in the long term for energy. Where only single-phase supply exists, single-phase is the practical solution.

Should I buy IE3 or IE4?

If the motor runs continuously for long hours daily, IE4's low energy loss pays for itself over time. For short-duration or infrequent use, IE3 is an economical and sufficient choice.

How quickly can I receive delivery from stock?

Because the most sought-after combinations are held in stock, lead time is quite short. When you share your need, we provide the stock status and fast quote at the same time.
