Abstract
A power transmitting system for an electric car includes a brushless DC motor of low speed and high torque and a speed altering transmitting device. The speed altering transmitting device consists of two transmitting shafts and a bevel gear set with two ends respectively connected to the two transmitting shafts. The brushless DC motor has a rotor positioned around the speed altering transmitting device, and a stator positioned around the rotor. Then the two transmitting shafts are combined with two bearings respectively in two bearing bases in a front and rear cap of the brushless DC motor. Then the rotation of the brushless DC motor is directly transmitted through the speed altering transmitting device to the wheels of an electric car, without using a speed reducing gear set.
