Military DC Motor

When the brush of this Military DC Motor is rotated through the rotor, “commutation” will occur mechanically. Mechanical commutation is simple, but slowly wears the copper commutator and graphite brush, creating an arc during operation and emitting electrical noise. However, this electrical noise can cause interference to other parts of the system, especially sensitive sensing and control systems.

Product features:

1. When the brush of this Military DC Motor is rotated through the rotor, “commutation” will occur mechanically. Mechanical commutation is simple, but slowly wears the copper commutator and graphite brush, creating an arc during operation and emitting electrical noise. However, this electrical noise can cause interference to other parts of the system, especially sensitive sensing and control systems.

2. Military DC Motor's maximum torque is generated at low speeds. At higher speeds, less current flows through the rotor windings due to their inductance, reducing the current consumed and the torque produced. If a current is applied, the DC motor will generate torque. If you want to control the position, you need to add a position sensor, such as a potentiometer or a magnetic encoder, and use this sensing value to achieve closed-loop control of the position.

3. Military DC Motor's rotor is rotated about the axis. The rotor is an electromagnet made by winding thin wires on two or more magnetic poles of a metal core. Its commutator is a pair of plates attached to the shaft. These plates provide two connections for the coils of the electromagnet. The commutator and brush can "flip" the electric field "a part of the motor".
