Description

1. Technical field

[0001] The invention relates to a direct-current motor, in particular to a program-controlled brushless direct-current motor operated by a preset fixed electromechanical program. 2. Background technology

[0002] As we all know, the basic conditions for the normal operation of brushless DC motors are: 1. After the power is turned on, the fixed magnetic poles and moving magnetic poles (permanent magnet magnetic poles and electromagnetic coil magnetic poles) of the motor are in any mutual position in the circumferential air gap magnetic field, and the interaction The electromagnetic vector resultant force F is greater than zero, otherwise the motor will have a dead point when starting; 2. Before the electromagnetic torque T interacting with the fixed magnetic pole after the moving magnetic pole rotates and approaches the zero position, the electromagnetic coil magnetic pole must be reversed, otherwise the motor efficiency will be low.
