As addition to the ESCON servo controller family, maxon motor now presents a miniaturized OEM plug-in module for sensorless BLDC applications. The compact, powerful 4-quadrant PWM servo motor controller offers efficient control of perma-nent-magnet activated sensorless BLDC motors (brushless DC motors, so-called EC motors) with-out Hall sensors up to approximately 200 Watts. The drift-free yet dynamic speed behavior enables speeds up to 120,000 rpm and provides extensive functionality with free configurable digital and analog inputs/outputs. It matches the company's motor range to suit high-demand applications and dynamic drive solutions and can be operated in speed controller (closed loop) and speed controller (open loop). The decisive factor is the low system complexity due to sensorless operation. The compact servo controller is controlled by an analog set value. It can be specified by means of analog voltage, by external or internal potentiometer, by defined value, or by means of a PWM signal with variable duty cycle. Other interesting features are for instance the ability to enable or disable the power stage de-pending on the direction of rotation as well as sensorless acceleration and deceleration by employment of defined speed ramps.
