maxon motor Escon Module 50/4 EC-S brushless DC motor controller

The latest brushless DC motor controller from maxon motor has dimensions of 43 x 11 mm. The easy-to-use product features an OEM plug-in style form factor for easy integration into new equipment designs.

Supporting existing controllers that require the motor to have a minimum of three hall sensors to operate, the device can be used with brushless motors that are not fitted with either hall sensors or an encoder. Despite this lack of feedback from the motor, the smart controller is still able to provide a closed loop speed control between the motor and control unit. A peak current of 12 A is available for up to 30 s on top of a continuous current rating of 4 A.

The voltage level excepted is anything between 10 and 50 VDC, which is particularly suitable for motor control applications with rapid deceleration rates and high levels of backfed energy. The motor controller is protected against winding short circuits, voltage spikes and overtemperature conditions. It is able to self-limit the amount of current the motor is allowed to draw from the motor control unit, which allows a motor to be driven to stall without burning out. There is a large amount of available I/O that can be set up with the free software package.
