NEMA17 7.0 Kgcm Stepper Motor for high torque applications. Ideal Motor for ATM machines, 3D printers, Peristaltic pumps and job positioning and rotating applications. Standard NEMA 17 frame size. 7.0 Kgcm bipolar configuration motor

 

RMCS-1102 is Rhino Motion Controls new and improved DSP based 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.

The RMCS-1102 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 using a DSP based PID current control loop.

The RMCS-1102’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.

 


Motor Specifications:

Drive Specifications:

  • Smooth and quiet operation at all speeds and extremely low motor heating

  • Industrial grade performance for 2-Phase Bipolar, 4-Phase and Uni-polar Stepper Motors

  • Input supply voltage from 15VDC to 42VDC ( The capacity of the drive is upto 50V DC however there is back emf generation during operation and this increases the total input voltage to more than rated voltage with a SMPS supply of higher than 42 V. For a 48V operation please select our drive RMCS-1101 as per following link: https://robokits.co.in/motors/stepper-motor/micro-stepping-stepper-motor-drive-18-80v-7amp )
  • Selectable peak coil current from 0.5A to 5A

  • Inaudible 20kHz current chopping frequency 

  • Selectable half-current during motor standstill to further reduce motor heating

  • Selectable micro-steps up to 20000 steps per rotation for a 1.8deg stepper motor and adjustable for bulk orders

  • Higher motor torque and higher speeds achievable due to advanced PID loop control algorithm

  • 2.5V, 3.3V and 5V compatible PULSE and DIRECTION inputs with 2-wire opto-isolated interface

  • Short-circuit protection for the motor outputs, over-voltage and under-voltage protection

  • LED indication for power and error states
