Product Description

KBS BLDC Motor Speed Controller

• Kelly KBS programmable BLDC motor controller provides efficient, smooth and quiet controls for electric motorcycle, golf cart, go-cart, 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.

Features:
• Intelligence with powerful microprocessor.
• Synchronous rectification, ultra low drop, fast PWM to achieve very high efficiency.
• Current limit and torque control.
• Battery current limiting available, doesn’t affect taking off performance.
• Low EMC.
• LED fault code helps user debugging.
• Battery protection: current cut back, shutdown and warning at high or low battery.
• Thermal enhanced rugged aluminum housing. Rugged connectors.
• Thermal protection: current cut back on low temperature and high temperature to protect battery and controller.
• Configurable 60-degree or 120-degree hall position sensor.
• Support any number of poles.
• Up to 40,000 electric RPM standard. Optional high speed 70,000 ERPM. (Electric RPM = mechanical RPM * motor pole pairs)
• Three modes of regen: brake switch regen, release throttle regen, 0-5V signal regen.
• Configurable high pedal protection: the controller will not work if high throttle is detected at power on.
• Current multiplication: Take less current from battery, output more current to motor.
• Easy installation: 3-wire potentiometer will work.
