Close Loop 24p 8 Pole BLDC Motor Driver With Variable Parameter Settings

24p 8 poles close loop of speed and current brushless DC motor driver with variable parameter settings

Without Heat Sink    

With Heat Sink

General Specifications:

1.Control signals:

F/R-----H or Open=Forward, L or Close=Reverse

EN------H or Open=Disable, L or Close=Enable

BK------H or Open=Running, L or Close=Brake

SV------0~5V speed reference(112K input resistance)

PG-----Speed pulse output(OC)

ALM---Alarm output(OC)

2. Hall sensors cable can not be tied together with windings cable.

3. Alarm conditions:

a. Hall sensor signals are not correct.

b. LV or OV for 2~3S.

c. Over temperature of case.

d. Over load for 6s continuously.

e. It can be reset by Turn-Off-On DC Power or Disable the driver once.

4. LED indicator:

P/A-------Bright=Driver is OK, Blink=Driver is in alarm

SHAFT----Bright=Motor shaft is moving, Dark=Motor shaft is in static

5. Braking operation:

The motor speed must be less than the safe brake speed Ns when you brake the motor.

For Y windings, Ns=√3 x Ip x RL x N/ (2 x Vp)

For △windings, Ns=IP x RL x N/ (2 x √3 x Vp)

Ip=Peak current(A), RL=Line to line resistance of windings(Ohm)

N=No-load speed(rpm), Vp=Rated voltage(V), Ns=Safe brake speed(rpm)

6. Driver setup by pot and switch:

R-SV pot=SV voltage ratio,  R-PC=Peak current ratio,SW1=Open/Close loop, SW2=Loop filter time,  SW3=Loop gain, SW4,5,6=Speed range setting, SW7,8=SV ramp time setting,

7. Peak current selection:

Ip>=2xIr or Ip>=4xPo/Vp, Ip is peak current of driver(A), Ir is rated current of motor(A), Po is rated output power of motor(W), Vp is rated voltage of driver(V)
