Servo Controller

As the third member, the ESCON 36/3 EC joins the one year ago launched series of maxon motor ESCON servo controllers. Its special design allows the setup of cost-optimized drive systems solely using Hall sensor feedback (no encoder necessary) without waiving the comprehensive 4-quadrant operation capabilities. It is designed for efficient control of BLDC motors (brushless DC motors, so-called EC motors) with Hall sensors up to approximately 100 Watts. The device has good control properties and a fast digital current controller with a high bandwidth for motor current/torque control. The drift-free yet dynamic speed behavior enables a speed range of 0 to 150,000 rpm. The controller provides a wide range of functions with fully configurable digital and analog inputs and outputs and can be run in various operating modes (speed controller (closed loop), speed controller (open loop), current controller). The servo controller is controlled by an analog set value specified via analog voltage, external or internal potentiometer, fixed value, or by means of PWM signal with variable duty cycle. Other features are, for instance, the ability to enable or disable the power stage depending on the direction of rotation, or to use speed ramps for acceleration and deceleration. The speed can be regulated with Hall sensors.
