  Control gp-dc series motor


Lanjiu MMT series electric vehicle controller is an efficient, stable and easy to install electric vehicle controller provided by lanjiu company for small and medium-sized electric vehicles. The main application objects are golf cart, trolley, electric motorcycle, hybrid electric vehicle, electric forklift, electric ship and industrial speed control motor control. The blue nine controller adopts high-power MOSFET high-frequency design, and the efficiency can reach 97%. The powerful and intelligent microprocessor provides the blue nine controller with comprehensive control. The user can also connect the computer and the controller through the connection line provided by us, configure the controller by himself, conduct the test and get the diagnosis information simply and quickly.

Blue nine MMT motor controller is a full bridge or four quadrant controller. It provides fast and reliable electronic direction control. There is no arc, spark or life limit when the motor direction changes.



performance index

1. PWM pulse width modulation

2. Speed regulation ratio: 1:60

3. Speed regulation model: R01---

Potentiometer (10K Ω / 2W) / signal isolator (0-5V, 0-10V, 4-20mA)


Pedal accelerator / hall handle

4. Input impedance: ≥ 10K Ω

5. Range of applied voltage: ± 25% of nominal voltage

6. Soft start time: 1-5s

7. Ambient temperature: - 10 ℃ ~ + 60 ℃

8. Environmental humidity: relative humidity ≤ 80rh. (no condensation)

9. Current limiting protection

10. Remote start stop

11. Suitable for permanent magnet, other excitation and series excitation motors

12. Overheat protection of the controller. When the controller overheats, the output current will fall back linearly, and the output current will not turn off suddenly

It can effectively protect the controller and driving safety.

13. The fault source can be directly determined by working led.

14. Stepless speed regulation and reverse brake control

15. The built-in precharge resistor and polarity protection diode are convenient for installation and use.

16. Undervoltage and overvoltage protection, effective protection of battery and controller assembly components

17. There is no acceleration signal input for 90 seconds, and the contactor electromagnetic coil power is automatically disconnected to save battery energy.

Note: it can be customized according to customers' requirements. For details, please consult customer service
