3 Phase Brushless Motor Controller (BLMD-03)
Product Description
Model Name: 3 Phase Brushless DC Motor Controller (BLMD-03)
PART 1: Electric parameter
PART 2: Describe for the function and performance
This three phase's brushless motor controller is designed with 120 degree of electric angle, when connect with this kind of brushless motor, it has some functions and performances as following:
2.1 Motor running and stop control (EN)
You can control the brushless motor to run or stop by controlling the terminal "EN" and "GND" connecting.
The motor will running when we connect the terminal "EN" to "GND"; when shut down, the motor will stop, and the stopping time will decided by the motor inertia and load add on the motor.
2.2 Motor rotation direction control (F/R)
You can control the motor rotation direction by controlling the terminal "F/R" and "GND" connecting.
When connect terminal "F/R" to terminal "GND", the motor will run at CCW (view from motor output side), and when shut down, the motor will run at another direction.
Attention: If you need to change the motor rotation direction, please stop the motor at firstly; otherwise the controller shall be caused to damage.
2.3 Break the motor to stop (BK)You can break the motor to stop if need. Motor can be running when the terminal "BK" not connect to "GND", but if you connect these two terminal together, motor will stop quickly. And the motor stopping time will decided by the motor inertia and load add on the motor.
Attention: If you are not necessary to stop the motor quickly, please don't use with this function since it has some electrical and mechanical impact on the motor and controller.
2.4 Speed control (SV)
You can control the motor running speed by controlling terminal "SV".
When connect the terminal "SV" to terminal "+6.25V", motor will run at maximum speed, and when "SV" connect to "GND", the motor running speed will be zero. You can adjust the motor speed from 0~maximun by a potentiometer, please refer to the diagram as follow:
2.5 Speed signal output (PG)
The speed pulse output port is 0C, output 30V/10mA max. You can connect with a resistance (3 K ohms ~10K ohm) between the signal and the input power to get the pulse signal, this port will output serial pulses which has fixed extent (it is 50US). This output pulse from every rotation of motor is 3 x N, "N" means the total pole number of the magnet.
2.6 Alarm output (ALM)
The alarm output port is 0C, output 30V/10mA max. You can connect with a resistance (3K ohm ~ 10 K ohms) between the signal and the input power to get the alarm signal. When alarm, this port and the GND connecting (Low voltage), and the controller will stop working and keep in alarm status.
