Variable Parameter Close Loop Brushless Dc Motor Driver With Heat Sink

Close loop of speed and current brushless DC motor drive with variable parameter settings and with heat sink

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)
