Ultra Low Voltage 5~18VDC Max current 10A, 20A, 50A, 100A High Current 2-Quadrant BLDC Motor Speed Driver


1. Surface-mount technology, small size, high current

2. 2-Quadrant PI close-loop control of speed or current with good linearity.

3. Variable parameter settings for different motors.

4. Control functions of safe reverse, safe start, enable, brake, speed reference and output functions of speed pulse(PG), alarm. Short circult and over temperature protection.

5. Three kinds of reference inputs: analog voltage, PWM, frequency.

6. Suitable for 3-Phase BLDC Motors with hall sensors.

7. Use of industrial grade chips.

Driver Numbering Information:

BLSD 24 35 WDC -2Q-H-T P

BLSD: BLDC Speed Driver

24: Rated Voltage(VDC)

35: Peak Current Limit(A)

DC=Normal DC Voltage, LDC=Ultra Low DC Voltage, WDC= Ultra Wide DC Voltage

2Q: 2-Quadrant Driving Mode

H: H series( High Current and Variable parameters)

T=-40~+65℃ Ta, Unlabelled=-10~+45℃ Ta

P=0~3KHz pulse input at SV, Unlabelled=0~5V at SV


1.Select peak current of driver: If the rated current Ir of motor is presented, then Ip(A)2*Ir(A)

If the rated output power of motor Pr(W) is presented, then Ip(A)≧4*Pr/Vr. Vr(V) is the rated voltage of motor

2. Driving quadrant: The drivers are only used in I&III quadrant.

3. Frequency input: The F-V transfer module can be added to the driver for frequency control(0-3KHz/TTL)at SV port

4. Brake operation: When BK port is switched to low level, motor will stop running quickly by shorting windings through bottom MOSFETs. The motor speed at braking must not exceed Safe-Brake-Speed Ns(see the connection diagram).

5. Interference from leads: The Hall signals can be disturbed by switched current in windings leads when length is more than 50mm. Don't intertwine them together. It is better to use shielded leads.

6. Motor Insultaion: Hall sensors to Windings/Hall sensors to Motor Cse/Windings to Motor Case

Insulation Resistance>100MOhm@500VDC

Dielectric strength<1mA@500VAC/50-60Hz/1 minute
