Energy storage motor for VD4 mechanism works and widely used

Mar 07, 2019

The energy storage motor of the VD4 mechanism is the principle that the alternating electromotive force induced in the armature coil is converted into a direct current electromotive force when it is taken out from the brush end by the commutation function of the commutator and the brush. The direction of the induced electromotive force is determined by the right-hand rule (the magnetic line is pointing to the palm of the hand, the thumb is pointing to the direction of movement of the conductor, and the other four fingers are pointing in the direction of the induced electromotive force in the conductor).

Working principle of energy storage motor for VD4 mechanism

The direction of the force applied to the conductor of the energy storage motor of the VD4 mechanism is determined by the left hand rule. This pair of electromagnetic forces forms a moment acting on the armature. This torque is called electromagnetic torque in the rotating machine. The direction of the torque is counterclockwise, in an attempt to rotate the armature counterclockwise. If this electromagnetic torque can overcome the resistive torque on the armature (such as the resistive torque caused by friction and other load torque), the armature can be rotated counterclockwise.


The DC motor of the energy storage motor of the VD4 mechanism is a motor that operates by a DC operating voltage, and is widely used in a tape recorder, a video recorder, a DVD player, an electric shaver, a hair dryer, an electronic watch, a toy, and the like. The stator magnetic pole (main magnetic pole) of the electromagnetic direct current motor is composed of a core and a field winding.
