high current 300A 400A Brushless dc controller 48V 3kw 4kw BLDC Motor Speed Controller

 

Model: KYEB48300

 

Product Description

 

KEYA  BLDC motor controller provides efficient, smooth and quiet controls for golf cart, go-cart, electric motorcycle, forklift, hybrid vehicle, electrical vehicle, electric boat, as well as industry motor speed or torque control. Motor speed controller uses high power MOSFET, PWM to achieve efficiency 99% in most cases. Powerful microprocessor brings in comprehensive and precise control to BLDC motor controllers. This programmable brushless motor controller also allows users to set parameters, conduct tests, and obtain diagnostic information quickly and easily.

1. Intelligence with powerful microprocessor.

2. Synchronous rectification, ultra low drop and fast PWM to achieve very high efficiency.

3. Electronic reversing.

4.Voltage monitoring on 3 motor phases, bus, and power supply.

5. Voltage monitoring on voltage source 12V and 5V.

6. Current sense on all 3 motor phases.

7. Current control loop.

8. Hardware over current protection.

9. Hardware over voltage protection.

10. Support torque mode, speed mode, and balanced mode operation.

11. Configurable limit for motor current and battery current.

12. Low EMC.

13. LED fault code.

14. Battery protection: current cutback, warning and shutdown at configurable high and low battery voltage.

15. Rugged aluminum housing for maximum heat dissipation and harsh environment.

16. Thermal protection: current cut back, warning and shutdown on high temperature.

17. Configurable 60 degree or 120 degree hall position sensors.

18. Support motors with any number of poles.

19. Up to 40,000 electric RPM standard. Optional high speed 70,000 ERPM, and ultra high speed 100,000 ERPM. (Electric RPM = mechanical RPM * motor pole pairs).

20. Support three modes of regenerative braking: brake switch regen, release throttle regen, 0-5V analog signal variable regen.

21. Configurable high pedal protection: the controller will not work if high throttle is detected at power on.

22. Current multiplication: Take less current from battery, output more current to motor.

23. Easy installation: 3 wire potentiometer can work.

24. PWMable reverse alarm output.

25. Remove fault code LED driver.

26. Current meter output.
