EV Motor – Hairpin Motor

We are capable to manufacture Motors for Electric Vehicles. We specialize in Hairpin Motor using permanent magnet.

Our technology is based on Japanese Model and is developed in collaboration with University and Research institute.

Our production machine is customized to ensure quality and use least amount of Battery Power.

hairpin motor refers to a type of electric motor that uses hairpin-shaped windings in the stator, as opposed to traditional coil windings. These motors are particularly gaining attention in electric vehicle (EV) applications, as they offer several potential advantages over traditional motors.

Key Features of Hairpin Motors:

  1. Hairpin Windings:
    • The windings are shaped like hairpins and are made from rectangular copper bars. These bars are inserted into slots in the stator.
    • The hairpin shape increases the space efficiency of the motor, allowing for more windings in a given area, which can enhance the motor’s power density.
  2. Improved Efficiency:
    • The use of hairpin windings allows for a more compact and efficient motor design. The rectangular shape reduces electrical losses due to the better utilization of space and less resistance than traditional winding methods.
  3. Enhanced Cooling:
    • The shape of the hairpin winding provides better opportunities for cooling since the copper bars can be arranged more effectively, improving thermal management.
  4. Higher Power Density:
    • By using hairpin-shaped windings, manufacturers can fit more windings in the same space, thus increasing the torque and power output of the motor.
  5. Reduced Production Costs:
    • While the initial investment in specialized equipment for making hairpin windings might be higher, over time, the reduced need for manual winding and the improved performance can lead to lower overall production costs.

Applications:

  • Electric Vehicles (EVs): Hairpin motors are increasingly used in electric vehicles because of their high efficiency, compact design, and potential for better performance. EV manufacturers are turning to hairpin motors to enhance the range and performance of their vehicles.
  • Industrial Motors: These motors are also used in various industrial applications where efficiency, power density, and size are critical.
