HOLRY 24V High Quality Low Voltage Brushless DC Speed Adjustable Driver

Introduction of brushless motor driver

The BLDC24 series brushless DC motor driver is independently developed by our company. It isaimed at high-tech products driven by medium-power and low-voltage brushless DC motors. The brushless DC motor driver adopts a cost-effective and low-cost solution. Automation control equipment, such as transmission equipment, medical equipment, packaging machinery, food machinery, fitness equipment, teaching equipment, garden machinery, and many other fields. The models are BLDC2405/BLDC2410/BLDC2420/BLDC2430; the drivers are suitable for the speed adjustment of three-phase brushless DC motors with a power of 24V-100W~1000W and can provide external potentiometer speed regulation, external analog voltage speed regulatio, upper computer(PLC,MCU) and other functions. At the same time, the driver has the characteristic of high torque start, fast start braking, forward and reverse switching, the combination of manual and automatic speed regulation, and abnormal alarm signal output.

Function description of brushless motor driver

(1) Speed regulation mode

A. The driver is externally connected to a potentiometer for speed regulation.

B. Analog voltage speed regulation: You can connect the two fixed terminals of the external potentiometer to the GND and 5V of the driver respectively, and connect the adjusting terminal to the SV terminal to adjust the speed with an external potentiometer(10K~100K)

(2) Motor forward/reverse control (F/R)

Controlling the on-off of F/R and GND can control the running direction. When F/R and GND are not connected, the motor runs clockwise, otherwise, the motor runs counterclockwise.

(3) Enable(EN)

The on-off of the control terminal EN relative to GND can control the running and stopping of the motor. When connected to the GND terminal, the motor runs, otherwise, the motor stops running.

(4) Brake stop(BK)

Control the on-off of BK and GND to brake and stop. When the control BK is connected to GND, the motor stops and locks, and when it is disconnected, the brake stops, and the brake stop is faster than the natural stop. The specific stop time is related to the load inertia of the user system

(5) Motor speed signal output (PG)

Speed pulse output: The output frequency F(HZ) will be output between this port and the port GND. The relationship between F and the motor speed N(RPM) is as follows: F=N*P/60, where P is the number of pole pairs of the motor, that is, every output pulse is the number of pole pairs of the motor.

(6) Alarm output 

Driver alarm output: When the ALM port alarms, this terminal is connected to GND (low level), and the driver stops working by itself and is in the alarm state.
