NSPBLDS4805 brushless DC motor driver is the latest high-tech product of our company for medium-power brushless motor. This product uses a large-scale integrated circuit to replace the original hardware design, with higher anti-interference and fast response. This product is suitable for driving any three-phase brushless DC motor, Hall or no Hall sensor, with peak current below 5A and power supply voltage between DC10V~50V. This driver features low temperature operation at high current. The products are used in a series of electrical automation control fields such as knitting equipment, medical equipment, food packaging machinery and electric power tools.
[Note] Due to the drastic changes in the temperature of the storage and transportation environment, condensation or frosting is likely to occur. The driver only can be powered on when the temperature of the driver is consistent with the ambient temperature after being placed in this environment for more than 12 hours.
Instructions for the terminal
power supply positive(Built-in power output)
External speed control signal, 0-100% of the motor speed adjustment through external potentiometer to change VSP voltage, 0~5V
Motor CW/ CCW rotation control ,CCW when connect DIR to GND,CW when not connect DIR to GND
Motor enable control, EN is connected to GND, allowing the drive to run; EN is not connected,prohibiting the drive from running.
Control signal power ground
Hall power supply positive
Hall sensor signal A phase input
Hall sensor signal B phase input
Hall sensor signal C phase input
HALL power ground
Motor and power
motor three-phase output signals
DC10V~50V power supply input
Speed control mode (VSP)
1. Connect with external potentiometer to adjust speed: connect the two fixed ends of the external potentiometer (5K~10K) to the GND and +5V terminals of the driver respectively. By connecting regulating terminal to the VSP terminal. The speed can be controlled by external potentiometer, or inputting analog voltage to VSP terminal through other control units (such as PLC, MCU, etc.). The voltage range of the VSP port is DC 0V~+ 5V, corresponding to the speed of motor from 0 to max speed.
2. Input PWM signal to adjust speed: connect PWM signal positive terminal to VSP terminal and negative terminal to GND. By setting the +5V PWM signal with the frequency of 10Hz-500Hz, through PWM duty cycle change to achieve speed adjustment.
CW/ CCW rotation
By controlling the high and low level transitions of DIR terminal to control rotation of the motor.
Note: In order to avoid huge impact to motor and mechanical equipment when motor changes direction suddenly at high speed, the drive decelerate the motor until it stops when DIR terminal receives commutation signal, then the motor changes direction and accelerates to the set speed.
By controlling the high and low level transitions of EN terminal to control RUN/STOP of the motor. Motor runs normally when EN is in low level and stops when in high. When the start/stop is used to control the motor to stop, the motor stops naturally. Its motion law is related to load inertia. Factory setting is EN for allowed operation.
