ABSTRACT:
A manually operated brushless DC motor is disclosed herein, which is an educational electric motor and can overcome the shortcoming hard to visualize the movement of a motor due to the high-speed rotation of the motor. The manually operated brushless DC motor according to the present invention provides two switches to replace the brushes used in a conventional motor. Users/learners have to alternatively press the switches to complete a closed circuit and drive the motor to rotate. Only when the rotor rotates in synchronism with the pressing rate of the switches, the rotor accelerates. Otherwise the rotation speed of the rotor decreases. The manually operated brushless DC motor provides the users/learners with the opportunity of viewing the rotor rotating in a slow motion, and the experience of manually operating the motor.
