Further attributes:
- usuable for brushless (BLDC) (direct current) motors without hall sensors or
when hall sensors are defect
(with [operative] hall sensors: please see our controllers MMT BLDC )
Controlling with hall sensors is preferring because of optimum motor's behavior
- Intelligent control by microprocessor
- powerful MOSFETs inside
- stepless control of speed/braking by seperate hall regulator 0-5V or potentiometer
- recuperation = regenerative braking energy
- brake switch regen, smooth; ABS
- reverse function = for- & backward, right + left turning, infinitely
- supports motor current limit, torque mode, speed mode, balanced mode (customizable)
- programmable over RS232 interface (MS Windows API)
 USB cable neccessary (upcharge)
- overvoltage and undervoltage protection
  
- overvoltage and undervoltage protection
- overheating protection (+ optional motor's thermistor)
- up to 17,000 electric rpms (ERPM)
- max. number of motor poles depending on motor's rpm
- wiring fault detection/overrun cut-off
- low EMC
- LED status / fault code
- housing material: aluminium; good heat-dissipating
- splash-water proof
- mounting holes
- CE & CCC certified
- legal warranty: 24 month

This offer refers to the entry - level model and without any options. Please send a message which model and optional features you wish: USB data cable?

Areas of applications:
This programmable, electronic reversible brushless sensorless motor controller with regenerative motor braking function (=eddy current brake / hysteresis brake) for BLDC direct current motors without hall sensors is suitable e. g. for e-scooter, tricycle, electric quad bike, rickshaw, trishaw, Velotaxi, park railway, ,go-cart, electric car, e-car, mini car, city car, golf cart, rider-controlled truck, forklift, lifting cart, theater engineering, stage engineering, industry, machines... .
This recuperation regulator manages the infinitely speed of electric BLDC motor , switches the motor's turning direction forward and reward and uses electric braking, what brings energy back to the batteries / accus.
This controller is programmable (soft-start, soft-stop, max. rpm / max. speed...)

Available accessories:

RS232-USB-Cable (you will receive an e-mail with the controller's programming software (win)),
BLDC Motor, lead acid battery, charger, hall regulator (hand trottle, thumb throttle, pedal), key switch, switch ...

Lead time / delivery time: approx. 20 working days.  

You also get commercial invoice & product warranty: 24 month (B2C) / 12 month (B2B).
