the armature

The working principle of armature in motors

The definition of the armature In electrical engineering, an armature is the component of an electric motor which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. The armature

What is varistor?

A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current-voltage characteristic that is similar to that of a diode. In contrast to a diode, however, it has the same character for both directions of traversing current. Traditionally, the varistor is composed of two rectifiers,

The classification of gear motor

Being a transmission device that is used widely, the gear motor mainly consists of the drive motor and the reducer. According to the transmission structure and application fields, gear motor can be mainly divided into large-scale gear motor, mini gear motor, gear reduction motor, planetary gear motor, dc gear motor,

What is the difference between a DC motor and an AC motor?

DC motor DC motors are powered from direct current (DC) power and are mechanically commutated machines. DC motors have a voltage-induced rotating armature winding, and a non-rotating armature field frame winding that is a static field or permanent magnet.   DC motors use different motor connections of the field and
