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:

  • The relationship between pole count and speed, and choosing the right speed for the application.
  • The difference between efficiency classes and when the IE4 range is advantageous.
  • What terms like IP55, Class F insulation and roughly 4% slip mean in practice.
  • Mounting types, shaft dimensions (for example Ø100 mm on the 355 frame) and body material selection.

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.
