Abstract

The present invention relates to a 24V direct current brushless motor controller. The controller mainly comprises an MCU, a display circuit, an external terminal, a driving circuit, an inversion circuit, a current feedback circuit and a Hall position detection circuit. The MCU is connected with the display circuit and the external terminal; the MCU is connected with the inversion circuit through the driving circuit, the inversion circuit is connected with the brushless direct current motor which is connected with the MCU through the current feedback circuit and the Hall position detection circuit; the brushless direct current motor is internally provides with an internal speed regulation circuit; and the MCU control signal motion logic is freely set and is directly connected with any one upper computer. The brushless direct current motor controller has three speed regulation modes of speed regulation of the internal speed regulation circuit, the speed regulation of external MCU control signals and the Hall speed regulation.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a 24V DC brushless motor controller. Background technique [0002] Brushless DC motors (BLDC) are widely used in daily life appliances, automotive industry, aviation, consumer electronics, medical electronics, industrial automation and other devices and instruments. As the name implies, BLDC does not use mechanical commutation brushes but directly uses electronic commutators. Compared with brushed motors, BLDC has many advantages in use, such as better torque and speed characteristics, high-speed dynamic response and high High efficiency, long service life and low noise. [0003] The traditional brushless DC motor controller adopts a fixed logic mode. For example, if the start signal is high level, the motor starts, and when the signal is low, the motor stops. The speed regulation method is single, and the control performance is average. Contents of the invention [000...
