NEMA42 Stepper Motor 110Kgcm Torque with RMCS-1101 Drive (RMCS-1156)

Ideal Motor for CNC machines and other machinery. Standard NEMA42 frame size. 110Kgcm bipolar configuration motor. Works well with RMCS-1101 Stepper Drive at 5Amp configuration.

RMCS-1101 is Rhino Motion Controls high power micro-stepping drive for 1.8deg Bipolar Stepper Motors. It is designed for smooth and quiet operation without compromising on torque and control at higher speeds. It has short-circuit protection for the motor outputs, over-voltage and under-voltage protection and will survive accidental motor disconnects while powered-up.

The RMCS-1101 achieves micro-stepping using a synchronous PWM output drive and high precision current feedback and this is absolutely silent when the motor is stopped or turning slowly. It virtually eliminates stopped-motor heating regardless of power supply voltage.

The RMCS-1101’s closed-loop control gains are calibrated on start-up based on motor characteristics and also adjusted dynamically while the motor is in motion. This control algorithm makes it capable of achieving better torque at higher speeds in comparison to comparable drives in its range.

The PULSE/STEP, DIRECTION inputs are optically isolated. Both inputs work with 2.5V, 3.3V or 5V logic drive signals. The input drive current is 5mA at 2.5V so almost all logic family (74LS, 74HC, etc.) can be used to drive these inputs. Each input provides individual anode and cathode connections to the opto-isolator allowing for multiple input drive interfaces.
