PM Motor Speed Controller
Kelly PM programmable permanent magnet motor controllers provide
efficient, smooth and quite controls for electrical vehicles like golf
cart, go-cart, electric motorcycle, scooter, fork lift, hybrid vehicle,
as well as electric boat and industry motor speed 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 brushed motor controllers. This programmable permanent
magnet motor controller also allows users to set parameters, conduct
tests, and obtain diagnostic information quickly and easily. Kelly PM
full bridge or 4 quadrant motor controller provides fast and reliable
electronic direction control. There is no arc, spark, or life limit on
motor direction changes.
Features:
•Intelligence with powerful microprocessor.
•Synchronous rectification, ultra low drop, and fast PWM to achieve very high efficiency.
•Current limit and torque control. Configurable torque mode and speed mode.
•Low EMC.
•LED fault code helps user debugging.
•Battery protection: Current cutback, shutdown and warning at low battery.
•Rugged aluminum housing for maximum heat dissipation.
•Thermal protection: Current cuts back at low temperature and high temperature to protect battery and controller.
•High pedal protection: Disable operation if power up with non-zero throttle.
•Brake switch is used to start regen.
•Able to control and change the motor’s running direction directly.
•Full Programmable with RS-232. Software upgradeable. Free Windows GUI software.
•Three modes of regen: brake switch regen, release throttle regen, 0-5V signal regen.
•No adjustment.
• PWMable Reverse Alarm.
• Brake Switch for regeneration.
• Analog Brake Input for continuous variable regeneration.
