A wrongly chosen motor means more than wasted money; it means faults, downtime and unnecessary energy use. We built this category so that you can make the right decision. Here you will find practical guides written from a manufacturer's field experience, explanations of key concepts and selection criteria. At HEM Motor our aim is not only to sell motors, but to determine the most suitable one together with you.
Some of the topics our content covers:
When choosing a motor, power, speed and efficiency should be assessed within the whole application rather than separately; a pump and a conveyor have very different needs. To clarify the speed and power combination, our power and speed options page is a good starting point. If you cannot find the information you need or remain undecided, tell us about your application and let our manufacturing engineers give you tailored technical guidance.

When selecting an electric motor, perhaps the most common first question is: "How many rpm do I need?" The answer to this question is directly related to the motor's number of pol... More Details
When ordering an electric motor there is one parameter as critical as power, speed and efficiency class, and it often comes to mind last: the mounting type. The mounting code (IM c... More Details
Selecting the right electric motor for a pump is not just about answering "how many kW?" The right selection is a chain that starts from the flow rate (Q) the pump must carry, move... More Details
Choosing the right reducer is the foundation of a machine running smoothly, quietly and for a long life. A wrongly chosen reducer either cannot provide the desired output speed, ca... More Details
In industrial plants, a large part of the electricity bill comes from electric motors. Pumps, fans, compressors, conveyors and countless machines run on motors that turn all day. T... More Details
An electric motor usually does not fail suddenly; it gives warning signs first. An abnormal noise, unexpected heating, increased vibration, or a burnt smell are all early warnings ... More Details
Selecting the right electric motor is far more than reading a kW value from a nameplate. A wrongly chosen motor either overheats and burns because it is undersized, wastes energy a... More Details
For someone looking at an electric motor nameplate for the first time, abbreviations like kW, rpm, IE3, IP55, IM B3, class F, S1 and cosφ read like a foreign language. Yet each of ... More Details
Connecting a three-phase electric motor correctly is critical both for the motor to run at the right voltage and for safe starting. The star (Y) and delta (Δ) connection determines... More Details
When a new electric motor arrives on site, the most common mistake made in the field is to connect the motor straight to the grid and press the button to see "does it run?" Yet cor... More Details
When it comes to selecting a motor for a facility, we are often confronted with catalogues full of options, and at first glance this variety can feel overwhelming. Yet the overwhel... More Details
When ordering an electric motor, most plants look only at power, speed and connection type. Yet ordering the motor on its own means completing just half of the investment. On the d... More Details
When a new electric motor comes off the truck, most operations carry it straight to the warehouse or assembly area, thinking "it's new anyway, nothing will go wrong." Yet the journ... More Details
When an electric motor that has run flawlessly in a plant for years finally burns out, the purchasing engineer almost always faces the same question: "This motor's brand is no long... More Details
In industry the most expensive motor is not the one with the highest price tag; the most expensive motor is the wrong one. A motor whose feet won't seat on the chassis, whose shaft... More Details
When buying an electric motor, the topic of warranty is brushed over in most talks with a single sentence: "two-year warranty." This sentence gives the buyer confidence, and usuall... More Details
In selecting an electric motor for machine builders, power and speed are usually calculated correctly; the real mistakes most often begin with a seemingly simple detail, namely the... More Details
