Description
Overview:
■PWM pulse width modulation technology, double closed loop of current and speed, high speed and low torque
Smooth operation.
■High-speed torque output is stable, the maximum speed is 8000rpm/min.
■Maximum 1:75 speed ratio, when matched with 4 pairs of brushless DC motors,
The minimum speed can reach 60rpm/min. The more motor stages, the higher the speed ratio
width.
■Flexible Hall magnetic pole position setting, 60°/300°/120°/240°
The electrical angle is optional and adapts to different specifications of the motor.
■ Provide two speed control modes: panel potentiometer reference, analog input
The child is given for user convenience.
■ Start and stop, fast braking, forward and reverse switching input signals (optical isolation).
■ Speed output, alarm output signal (optical isolation, OC gate output).
■ Over-current, over-voltage, blocked, motor out of control alarm.

In the picture:
TX is an isolation transformer that determines its parameters based on the power supply load. In general, the output voltage of the transformer is determined according to the output DC voltage requirement.
The DC voltage after filtering is VDC+=l.414×Vout. When used in the BLDC-5020 driver, the recommended voltage output is AC21 ~ 28V.
Among them: the transformer capacity is determined according to the load current: Cl is the electrolytic capacitor, the recommended parameters are: 100V/2200uF: C2 is the non-inductive surge absorption
The recommended parameters are: 400V/0.22uF: The Dl rectifier bridge parameters are based on the load current and output voltage.
