• Uses 5K POT or Hall-effect throttles.
• Direction reverse; either by Pot (Pot center-stop, clockwise forward
and anti-clockwise reverse) or by a toggle switch(Pot used for speed).
• Aluminum enclosure as standard package; optionally Potted.
• Specified as BLDC voltage- Current limit. For example BLDC24V-50A.
• Brake input: cuts motor power when a brake contact closes.
• Tachometer output: produces pulses at motor RPM rate.
• Over-current and over-temperature protected.
• Applications for hub motors used in electric bikes, scooters,
motorcycles, min-cars, etc.
DESCRIPTION:
These controllers output 3-phase AC to drive a brushless DC motor as function of Hall-Effect sensors of the
motor.
They are used for industrial brushless DC motors as well as brushless Hub motors of modern EVs.
They are electronically reversible by 2 methods (specify); either by the throttle Pot only (stop for Pot center,
forward when Pot is set above center and reverse when Pot is below its center) OR by a toggle switch (Pot
used for speed only).
They feature extra signals; such as brake input (to cut the motor power) and tachometer output for EV
speedometer.
Also they have internal HV to 12V converter to power the key switch.
TECHNICAL SPECIFICATIONS:
- Input Battery Voltage: ordered for 24 to 360V battery
- 5K Pot or Hall-effect type throttle compatibility (specify which)
- Motor Current: ordered for current limits in 30 to 300A range, above which over-current protection cuts the
power.
- Motor Power Wiring: 3 power wires which output 3-phase AC to the motor.
- Motor Position Sense: 5 -wires; 5V, GND and 3 sensor position readings.
- Closed contact for Brake input, it cuts the power to the motor.
- Tachometer 12V pulse; at the rate of motor RPM.
- Optional auxiliary signals: customized per customer requirements such as control of vehicle lights, etc.
- Over current and over-temperature protected

2. EVRTC Bi-Directional (4- Quadrant) Controller
1. EVMTC line of DC Motor Controllers
Please order them as: EVMTCvoltage- Current limit; e.g: EVMTC72V-200A for 72V with 200A current limit.
These controllers are unidirectional but can be easily made bidirectional (reversible) by external contactors.
