ELECTRIC MOTOR POWER DEVICE Russian patent published in 2022 - IPC H02M3/18 B60L50/50 

FIELD: electric motors power supply.

SUBSTANCE: invention relates to power supplies for electric motors, which are elements of actuators that convert electrical energy into mechanical energy. The circuit of automatic parallel connection of the capacitive storage through the diode and current limiters of the capacitive storage is introduced into the power supply of the electric motor. The capacitive storage current limiter is controlled by feedback from another motor current limiter and allows the capacitive storage to be used during peak motor loads while charging it only when the motor load is not high. The objective of the invention is to create a power supply device for an electric motor with compensation for the voltage drops generated by it at high load currents.

EFFECT: increasing the dynamic properties of the operation of the electric motor from an autonomous power source at high load currents and reducing the power, weight and dimensions of the autonomous power source.
