Performance Requirements Of DC Motors For New Energy Vehicles

The motor is an important driving force for new energy vehicles, what are the requirements for the performance of the motor? Here is a brief introduction for you.
1. Anti-vibration
Since the armature of a DC motor is heavy, vibrations from the road can affect the mechanical stress to which the bearings are subjected, so it is important to monitor this stress and implement appropriate countermeasures. The sliding contact between the commutator and the brushes is also susceptible to vibration, so preventive measures such as increasing the stored preload of the brush springs are required.
2. Environmental adaptability
When a DC motor is used as a drive motor for a new energy vehicle, the environment in which it is used is basically the same as when it is used outdoors. DC motors must be designed with full consideration of sealing to prevent dust and water vapor from entering the motor, as well as the heat dissipation performance of the motor.

3. Low energy consumption
It is vital to keep the DC motor low loss and high efficiency so that the range of primary charge can be increased and the temperature rise of the motor can be reduced.
4. Resistance to load fluctuation
When a car is driven under various road conditions, the load on the motor can change greatly, so attention must be paid to how the rated operating conditions are determined and how the commutation poles and compensation windings are designed.

5. Small and Lightweight
In order to gain more space in the vehicle and reduce the overall mass of the vehicle, miniaturization and lightweighting of the drive motor has become an inevitable trend.
6. Maintenance-free
Design a larger inspection port and use brush materials that will not harm the commutator to increase the brush life and make maintenance and replacement easier.
