Application guidelines:
- Confirm that the voltage and power parameters of the motor not
exceed the range as specified.
- Applicable to hall brushless dc motor with Hall at 120°, not all
manufacturers' Hall line sequence are corresponding, you can adjust
the Hall line sequence or motor three-phase line sequence according
to the actual situation, to achieve the best driving effect.
- JYQD-V7.0 is driver board without housing and heatsink, it can
drive the motor below 36 watt without any heatsink, but needs
normal ventilation.
- The 5V output port on the drive board is forbidden to connect
external power equipment. It is only applicable to external
potentiometer or switch for speed adjustment, commutation and
enabling operation
Note:
A) Before application, make sure that your motor operating voltage,
current and speed match the control board.
B) Before powering on, be sure to check that the polarity of the
power supply is correct and if there is a short circuit
C) the motor from start to run, if the heat is serious, the current
exceeds the normal value, and the speed does not go, you need to
immediately stop the acceleration, and disconnect the power
Wiring diagram:
1. Control port
5V —Driver board internal output voltage, external potentiometer or
switch for speed adjustment and reversing operation
Z/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.
VR —Speed control port. Analog voltage linear speed regulation 0.1v
-5V, The input resistance is 20K Ohm ,connect with GND when input
PWM speed regulation, PWM frequency:1-20KHZ; Duty cycle 0-100%
SC—Enable port control. Connect 5V or no connect to allow
operation, connect GND to forbid operation.
GND—Used for Drive board internal control
2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
GND----DC-
VCC----DC +
3:Hall sensor port
Ha--- Hall a
Hb---Hall b
Hc---Hall c
GND---GND
5V---5V output
4. Use shielded wires if the drivers board has more than 50 cm
distance from the motor, otherwise it may lead to abnormal driving,
affecting the normal use.
5. Control port distance: 2.54mm,Power port distance:2.54 mm
6. Pay attention to the insulation between the driver MOSFET and
the heatsink or the installation plate.
Failure and exclusion:
A) The motor can not start normally: Please check the power supply
is normal, the motor connection is correct, the speed voltage is
normal, the enable side is high
(Enable side in the normal use should be 5V, when the energy can be
0V)
B) Hall phase sequence does not match the motor windings, adjust
the three Hall lines until the motor runs smoothly
