One of the most sought-after small-power classes, the 0.75 kW electric motor, appears in pumps, fans, gearbox inputs, conveyors and countless machine-tool applications. HEM Motor supplies motors in this rating directly from the manufacturer, from stock and with an advantageous price-performance balance. In the 80 frame size, 2, 4 and 6-pole options, B3 foot-mounted, B5 and B14 flanged connection types and IE3 / IE4 efficiency classes are all available from a single source. On this page you will find speed, frame, connection and efficiency options in 0.75 kW motor sales, the single-phase versus three-phase difference, the stock advantage and our fast quotation process. The information below will guide you to select the right motor quickly and buy it from the manufacturer at a competitive price.
Speed, Frame and Connection Options in 0.75 kW Motor Sales
The first factor that determines the suitability of a 0.75 kW motor is the speed, that is, the pole structure. 2-pole models rotate at high speed, around 3000 rpm, and are preferred in small pumps, blowers and exhausters. 4-pole 0.75 kW motors at around 1500 rpm are the most common option and serve almost as a standard for conveyors, gearbox inputs and general drives. 6-pole models at around 1000 rpm suit applications requiring lower speed and a smoother start. Motors in this rating are mostly produced in the 80 frame size with standard IEC connection dimensions, which makes a one-to-one replacement of an existing motor easy.
The connection type is also decisive. B3 foot-mounted motors are bolted to the floor or a base and are used in classic machine and conveyor mountings. B5 large-flange models connect directly to a gearbox or pump via the large flange. The B14 face-flange small-flange option is ideal for tight mounting spaces and light transmission. In our stock sales we offer all three connection types together with power and speed combinations so that you can obtain the right motor quickly.
Which Connection Type Suits Which Application?
| Connection Type | Typical Application | Mounting Advantage |
|---|---|---|
| B3 Foot | Conveyor, machine tool, general drive | Easy base fixing |
| B5 Large Flange | Gearbox input, pump | Direct flange connection |
| B14 Face Flange | Tight space, light transmission | Compact mounting |
IE3 and IE4 Efficiency Class: the Right Choice at 0.75 kW
Even at small powers the efficiency class matters for both regulatory compliance and operating cost. IE3 premium efficiency motors are widely stocked at 0.75 kW and are the right choice for most general-purpose applications. For machines that run continuously for most of the day, IE4 super premium efficiency 0.75 kW motors reduce energy consumption further and strengthen the price-performance balance in the long term. As HEM Motor we supply 80 frame 0.75 kW motors in both efficiency classes directly from the manufacturer and guide you in selecting the right class for your application.
Factors that influence the efficiency-class choice include daily running hours, load ratio and how critical the application is. While IE3 is sufficient for a rarely used standby machine, the energy gain of an IE4 motor stands out in continuous shift production. For a broader power-speed table and stock information you can review our small-power stock guides and clarify your speed and pole selection.
Single-Phase or Three-Phase? Supply Selection at 0.75 kW
0.75 kW is a critical power point where the transition between single-phase and three-phase supply takes place. Three-phase (380/400V) 0.75 kW motors are preferred in industrial plants and anywhere a three-phase grid is available; they provide higher efficiency, lower vibration and trouble-free starting. Single-phase (220V) 0.75 kW motors are used in workshops, small businesses and domestic machines without a three-phase grid; they run with capacitor starting. We determine the correct supply type according to the electrical infrastructure of your location and offer both options from stock.
- Three-phase 0.75 kW: Industry, continuous operation, high efficiency and low vibration
- Single-phase 0.75 kW: Workshop and small business, single-phase grid, capacitor start
- 2-pole (3000 rpm): Small pump, blower, high-speed applications
- 4-pole (1500 rpm): The most common choice, gearbox and conveyor input
- 6-pole (1000 rpm): Applications requiring low speed and a smooth start
The Most Common Applications of the 0.75 kW Motor
Despite its small power, the 0.75 kW electric motor is a fundamental drive element across a very wide part of industry. Small centrifugal pumps, booster first stages, circulation pumps and dosing pumps are frequently chosen at this rating. In ventilation and exhaust applications, small exhausters, duct fans and cabinet fans are driven by a 0.75 kW motor. In wood and metal workshops, small machine tools, grinding and polishing units, and the feeding and winding units of packaging machines are also common uses of this power class. Combined with a gearbox, it becomes an ideal input motor for obtaining low output speed in small conveyors, mixers and dosing systems.
Selecting the right motor across such a wide range of applications requires evaluating not only the power but also the speed, connection type, protection class and efficiency class together. For example, IP55 and higher protection matters for a 0.75 kW motor working in a dusty workshop, while the IE4 efficiency class stands out in a continuously running circulation pump. As HEM Motor we evaluate your application requirements together, quickly determine the most suitable 0.75 kW motor from our stock and speed up the quotation process.

To benefit from the stock advantage you can reach our 0.75 kW IE3 product group through IE3 efficient asynchronous electric motors, and the IE4 options through our standard electric motors page. If you prefer to select by connection type, our B5 flanged electric motors and B3 foot-mounted electric motors pages make finding the right motor easier.
Frequently Asked Questions About 0.75 kW Electric Motor Sales
How many horsepower does a 0.75 kW motor correspond to?
0.75 kW corresponds to approximately 1 HP (horsepower). For this reason it is also searched as a "1 HP motor". A 1 HP motor requirement stated in HP on imported machines is met one-to-one by a 0.75 kW IEC motor.
In which frame size is the 0.75 kW motor produced?
0.75 kW motors are mostly produced in the 80 frame size. Both 4-pole and 2-pole models are offered in the 80 frame with standard IEC connection dimensions, which makes one-to-one replacement of an existing motor easy.
Is a single-phase 0.75 kW motor as efficient as three-phase?
Three-phase 0.75 kW motors generally offer higher efficiency and lower vibration. If you have a three-phase grid we recommend choosing three-phase; single-phase is suitable only for workshops and small businesses with a single-phase grid.
Should I buy IE3 or IE4 in a 0.75 kW motor?
IE3 is sufficient for rarely used standby machines. For machines running continuously most of the day, the energy saving of an IE4 motor strengthens price-performance in the long term. When you share your running hours we determine the right class together.
Is the 0.75 kW motor in stock, and how quickly is it delivered?
As 0.75 kW is one of the most-requested powers, we keep broad stock in 2/4/6 poles and different connection types. When you share your need, we supply your motor with a fast quotation and short delivery time.
