Motion Control Maxon

Maxon ESCON controller features a wide range of functions, with fully configurable digital and analog inputs and outputs.

Maxon’s introduced its ESCON 36/3 EC, a 4-quadrant PWM servo controller designed for control of BLDC motors (brushless DC motors, so-called EC motors) with Hall sensors up to approximately 100 Watts. The controller has a speed range of 0 to 150,000 rpm and can be run in various operating modes (speed controller (closed loop), speed controller (open loop), current controller).

The unit is controlled by means of an analog set value that can be specified by means of analog voltage, an external or internal potentiometer, a defined value or by means of a PWM signal with variable duty cycle. In addition, the contoller requires no additional external filters or motor chokes for operation.

The ESCON 36/3 EC has protective circuits against over current, excess temperature, under- and over-voltage, against voltage transients and against short-circuits in the motor cable. It is equipped with protected digital inputs and outputs and an adjustable current limitation for protecting the motor and the load. The motor current and the actual speed of the motor shaft can be monitored by means of the analog output voltage.
