How to Select an Efficient Electric Motor?

Choosing an ideal electric motor is not at all an easy task. Only looking at the price can be the biggest mistake you can make. There are a lot of other things that one needs to consider.

If you want to buy an efficient electric motor, then review the following given details.

  1. Vehicle’s characteristics – The first and the most important thing that you have to do before buying an electric motor is to study your vehicle and its different aspects. Various properties of the vehicle such as weight, size, aerodynamics, and overload are crucial as they are helpful in deciding torque, speed and power requirements of the electric motor. So, make sure to consider these characteristics as they will help in selecting the most suitable electric motor.
  2. Where and how you drive the vehicle – How the vehicle is used plays a significant role in the electric motor purchasing process. What will be the regular driving cycles of the vehicle? Will it be driven in an urban area with several stops? Will it be driven on long ways with only a few stops? All of this will assist in determining the vehicle configuration and battery pack size and eventually affect the choice of the electric motor.
  3. Vehicle’s configuration – The configuration of the vehicle can be either hybrid or fully electric. In the case of hybrid, it can be either series hybrid or parallel hybrid. If the routes of the vehicle are not predictable or if it will be driven on long ways, then the hybrid configuration is preferred. And when the distance is short, and stops are more, then the electric configuration is the right choice.
  4. Maximum torque – The maximum torque enables the vehicle to start on a given slope. You need to discover the highest grade the vehicle will need to climb. Using this grade, you can measure the highest required torque by the electric motor. Additionally, don’t forget to consider the maximum weight.
  5. Maximum power – Under stringent slope and speed conditions; it is the maximum power that let the vehicle to reach and maintain a consistent speed. Thus, it is crucial to study the maximum power of the vehicle. A simulator is needed to calculate the maximum power. In addition to the forces required for climbing, it considers the drag and friction coefficients of the vehicle.
  6. Battery Voltage – The battery voltage is reliant on the size of the vehicle. As the battery voltage rises, the current output is decreased. So, where the vehicle’s continuous power is high, you have to keep the size of the conductors at a manageable level by increasing the battery voltage.
  7. Cost – Buying something without considering your budget is never a good idea. So, make sure to set your budget first and review the different electric motors afterwards.
