Electric Motor Build Make a Simple Electric Motor


An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

Learn to build a simple electric motor as well as how the motor works. We cover the rotor, shaft, commutator, stator and magnets to learn how an electric motor works. We 3D print the components also.

Typical brushless DC motors use one or more permanent magnets in the rotor and electromagnets on the motor housing for the stator. A motor controller converts DC to AC. This design is mechanically simpler than that of brushed motors because it eliminates the complication of transferring power from outside the motor to the spinning rotor.


The motor controller can sense the rotor’s position via Hall effect sensors or similar devices and can precisely control the timing, phase, etc., of the current in the rotor coils to optimize torque, conserve power, regulate speed, and even apply some braking./ The Engineering Mindset
