Servo motor controller supports sensorless operation of BLDC motors
14.00
With a claimed efficiency of 97%, the compact 4-quadrant PWM servo motor controller is suitable for permanent-magnet activated sensorless BLDC motors (brushless DC motors, so-called EC motors) with-out Hall sensors up to approximately 200 Watts. The plug-in module’s drift-free and extremely dynamic speed behaviour enables speeds up to 120‘000 rpm and provides extensive functionality with free configurable digital and analogue inputs/outputs.
It matches maxon’s motor range to suit even highest-demand applications and dynamic drive solutions and can be operated in speed controller (closed loop) and speed controller (open loop). The servo controller is controlled by an analogue set value. It can be specified by means of analogue voltage, by external or internal potentiometer, by defined value, or by means of a PWM signal with variable duty cycle. The ESCON Module 50/4 EC-S features protective circuitry against overcurrent, excess temperature, undervoltage and overvoltage, voltage transients and short-circuits in the motor cable. It also is equipped with protected digital inputs and outputs and adjustable current limitation to protect motor and load.
