The RBK Series combines a high current, bipolar stepper motor with a DC input microstepping driver.
  • Microstep driver electronically divides basic step angle of the motor (1.8º/step) by up to 128, 16 different resolutions level are available.
  • Includes Oriental Motor's proprietary Smooth Drive Function to easily achieve low vibration operation.
  • High-torque type motor
  • Encoder model
  • Lead wire/connector assemblies of 0.6 m (2 ft.) for motor and encoder are included with the package.
