JUYI Tech 12V-36V Dual BLDC Motor Controller For Two BLDC Motors with Brake Function And PWM Control

12-36V DC JYQD-YL02D (updated version of JYQD-YL02C) brushless motor controller for wheelchair,hub motor,electric scooter,electric skateboard,etc.

JYQD-YL02D is the new model of JYQD-YL02C, the newest model is JYQD-YL02D!!!

It has four versions for your choice, please choose the right version you want when you place an order

JYQD-YL02D(8559) direct start version has NO LOCK function,(linear speed regulation 0-5V,liner brake:0-5V)

JYQD-YL02D(457E) direct start version has NO LOCK function,(linear speed regulation 0-2.5V,liner brake:0-2.5V)

JYQD-YL02D(99F2) safety start version has LOCK function.(linear speed regulation 0-5V,liner brake:0-5V)

JYQD-YL02D(C737) safety start version has LOCK function.(linear speed regulation 0-2.5V,liner brake:0- 2.5V)

Safety start: if you use a knob~style potentiometer to adjust the speed, if the potentiometer not rest to 0 before stop,the motor will direct start according

Important reminder:

1:Different Hall effect sensored BLDC motor has different Hall wires sequence, please do well-match before onload drive.

2: Add heatsink if the power more than 100W and keep good heat dissipation conditions for the board.

Application notes:
1. Confirm that the voltage and power parameters of the motor not exceed the range of the driver board as specified.

2. This driver board is used for 3-phase brushless sensorless motor, but not suit for all 3-phase brushless sensorless motors directly.The
hall angle should be 120 degrees.

3. The brake function of JYQD-YL02D is reactive brake.The motor turns the brake to produce energy for recycling.Please don’t use the brake function when testing with a regulated power to avoid damage driver.

4. The 5V output port on the driver board,can be controled by the Single-chip Computer with the current lower 300MA.

5. Pleasse pay attention to the insulation and heat dissipation about the driver board.

6. Safety start function:If the speed regulation is not in right place or the speed rehulation is invalid after power-on, please make the speed regulation or brake reset can be ok.

1. Control Port (Left)2.0 hole spacing
5V--Driver board internal output voltage,can provide external current<300MA.

2EL--Brake control port,reactive and linear brake with energy
recovery function,analog voltage brake 0-5V.In the case of constant speed+, the higher the braking voltage, the greater the braking force 0-100%.

2M--Motor speed pulse signal output port,the pulse frequency is proportional to the motor speed.(The pulse ratio is related to the motor)
2Z/F--- Rotating direction control ports. Connect “5V” high level or no connect is Forward direction, connect 0 V low level or connect to GND is reverse direction.

2VR--Speed control port.Analog voltage speed regulation 0V- 5V(0-2.5V),Linear speed adjustment from low to high.connect
with GND when input PWM speed regulation.

GND--Used for Drive board internal control.

2. Hall port(Left) 2.0 hole spacing
GND - Negative pole of hall power
2Hc - motor Hall signal C
2Hb - motor Hall signal B
2Ha - motor Hall signal A
5V - Positive pole of hall power

3. Power port(Left)
P - DC Power- MA- Motor phase A
MB- Motor phase B
MC- Motor phase C

4. Power port(Right) 2.0 hole spacing
GND- Used for Drive board internal

1VR- Speed control port.Analog voltage speed regulation 0V-5V(0-2.5V),Linear speed adjustment from low to high.connect with GND when input PWM speed regulation.

1Z/F- Rotating direction control ports. Connect “5V” high level or no connect is Forward direction, connect 0 V low level or connect to GND is reverse direction.

1M - Motor speed pulse signal output port,the pulse frequency is proportional to the motor speed.(The pulse ratio is related to the motor)
1EL - Brake control port,reactive and linear brake with energy recovery function,analog voltage brake 0-5V.In the case of constant speed+, the higher the braking voltage, the greater the braking force 0-100%.

5V - Driver board internal output voltage,can provide external current<300MA.

5. Hall port (Right) 2.0 hole

5V - Positive pole of hall power
1Ha- motor Hall signal A
1Hb- motor Hall signal B
1Hc- motor Hall signal C
GND- Negative pole of hall power

6. Power port (Right)
P+ -- DC Power +
1MC- Motor phase A
1MB- Motor phase B
1MA- Motor phase C

7. Use shielded wires if the drivers board has more than 50cm distance from the motor, otherwise it may lead to abnormal driving, affecting the normal use.

8. Pay attention to the heat dissipation if continue working with the max. Current.
