Maxon ESCON 36/3 EC is a 4-quadrant PWM servo controller designed for efficient control of BLDC motors (brushless DC motors, so-called EC motors) with Hall sensors up to approximately 100 Watts. Product provides improved control properties and a fast digital current controller with a large bandwidth for optimal motor current/torque control. The drift-free behavior enables a speed range of 0 to 150,000 rpm. Product provides a wide range of functions, with fully configurable digital and analog inputs and outputs. Unit can be run in various operating modes (speed controller (closed loop), speed controller (open loop), current controller).
