Abstract

The invention relates to a direct current motor and a control circuit thereof, belonging to the field of power units. The direct current motor comprises a main shaft (1), an on-off device (2), an enclosure (6) and a magnet holder (9), and is characterized in that the main shaft (1) is provided with the magnet holder (9), the main shaft and the magnet holder are coaxially and fixedly connected by a shaft sleeve (10), the magnet holder (9) is evenly provided with 20 grooves, and permanent magnets (7) are arranged in the grooves; the inner wall of the enclosure (6) is fixedly provided with an electromagnet (8), and the on-off device (2) and the main shaft (1) are coaxially and fixedly connected. The direct current motor and the control circuit thereof solve the technical problem that a conventional direct current motor rotor part is electrified and results in maintenance and overhauling difficulties, and have great practical application value.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a DC motor and its control circuit. Background technique [0002] At present, most of the existing DC motors use a commutator and a brush device to continuously change the current in the coil to form an electromagnetic force, so that the rotor is forced in the stator magnetic field to generate torque, and then the rotor rotates. However, the rotor part of this motor is in a charged state, and the brush device and commutator must continue to slide to change the current in the armature coil to make the motor continue to rotate. The process is very cumbersome, prone to electric sparks, serious mechanical wear, prone to failure, inconvenient maintenance, complex structure, and high cost. Contents of the invention [0003] The embodiment of the present invention provides a DC motor and its control circuit, so as to at least solve the technical problem of difficult maintenance and overh...
