TMCM-171 Single Axis BLDC Motor Controller / Driver with Encoder 20A / 48V

Description
The TMCM-171 is a controller/driver module for high performance servo drives based on brushless DC motors combining the high resolution of a stepper motor coupled with the high dynamic, high velocity and high reliability of a BLDC drive.
The motor and switches can be connected easily with pluggable screw terminals and a build-in ramp generator allows parameterised smooth positioning. The TMCM-171 supports BLDC motors with nearly any number of poles and incremental encoders with nearly any resolution can be accommodated.  The TMCM-171 integrates a velocity regulator, a position regulator and a ramp generator and the module can be controlled remotely via CAN or RS-485 interface. In addition the TMCM-171 is equipped with a step direction interface and stand alone operation (either via TMCL programme or via analogue control) is available.
