Basic structure and wide application of VS1 mechanism supporting DC motor

Jun 27, 2019

The VS1 mechanism supporting DC motor is a motor that converts DC power into mechanical energy during the working process, and is widely used in electric power drag because of its good speed regulation performance. The DC motor is divided into permanent magnet, overexcitation and self-excitation according to the excitation mode. The self-excitation is divided into three types: shunt excitation, series excitation and re-excitation.


When the DC motor of the VS1 mechanism is supplied with power to the electric armature winding through the brush during operation, the N-pole lower conductor on the armature surface can flow through the current in the same direction. According to the left-hand rule, the conductor will be subjected to the counterclockwise torque. The conductor on the armature surface S also flows through the same direction of current, and the conductor will also be subjected to a counterclockwise moment according to the left-hand rule. Thus, the entire armature winding, that is, the rotor, will rotate counterclockwise, and the input DC power is converted into mechanical energy output on the rotor shaft. It consists of stator and rotor, stator: base, main magnetic pole, commutating pole, brush device, etc.; rotor (armature): armature core, armature winding, commutator, shaft and fan.


Basic structure of DC motor for VS1 mechanism


It is divided into two parts: the stator and the rotor. Note: Do not confuse the commutator with the commutator.


The stator includes: a main magnetic pole, a base, a commutating pole, a brush device, and the like.


The rotor includes: an armature core, an armature winding, a commutator, a shaft and a fan.
