Maxon Motor is launching the Escon 36/2 DC as the first member of a new servo controller family. As a 4-quadrant PWM servo controller for controlling brushed permanent magnet DC motors up to around 72 W, it has an above-average power density and, with its dimensions of just 55 mm × 40 mm × 16.1 mm, is virtually synonymous with the degree of miniaturization currently possible in servo controller technology, according to the supplier. The drift-free, but at the same time very dynamic speed behavior allows a speed range between 1 and 150,000 rpm. The digital and analog inputs and outputs are freely programmable. The controller is commanded via an analog setpoint. This can be specified using an analog voltage, an external or internal potentiometer, a fixed value or a PWM signal with a variable duty cycle. Other functions include enabling or disabling the output stage depending on the direction of rotation as well as acceleration and deceleration using a defined speed ramp. The speed is controlled by means of a digital incremental encoder (2-channel with/without line driver), DC tacho or without encoder (IxR compensation). Once the controller has been connected to the PC via the USB interface, it can be easily parameterized using the "Escon Studio" graphical user interface.
