The electric motors that generate power to rotate the wheels of the train are known as traction motors. The turning force produced by the traction motor is transmitted to the wheels of the train through the driving gear unit and axle. Traction motors should have high efficiency.
Desirable Characteristics of Traction Motors:
- High Starting Torque: Required to overcome initial inertia and move the vehicle from rest.
- Good Speed Control: Ensures efficient acceleration and deceleration.
- Regenerative Braking Capability: Helps recover energy during braking and improves efficiency.
- Compact & Lightweight Design: Important for space efficiency, but not the most critical mechanical characteristic.
Thus, high starting torque is the most desirable mechanical characteristic for traction motors.
