    Water Cooling Motor

    Generally, smaller motors use air cooling to reduce the surface temperature of the motor housing to achieve heat dissipation. However, for high-torque drive motors such as 10-12m electric buses/tourist buses, if the air-cooling method is still used, the heat dissipation effect of the motor will be relatively poor. The operating temperature of the motor is usually 90°C, which affects the motor efficiency And reduce the life of the motor. The water-cooled drive motor designed by our company does not have a heat sink on the outer surface of the casing, which reduces the size and weight of the motor and facilitates the layout of the car chassis. And because of the reduction in weight, battery energy can be saved, and the driving range of electric vehicles can be extended. Motor features: high-torque regenerative braking has high recovery efficiency, low water-cooled heat dissipation temperature rise, shock resistance, high reliability, and long service life.
