Large torque by strong neodymium magnetsLow torque ripple by optimum magnetic circuit designStandard models applicable to both 200V and 400V inputHigh speed models is also applicable for turningHigh speed and high precision and maintenance free by the direct drive Suited to rotary tables and additional axes of 5-axes machine tools etc.
*)“S” of DiS means “Strong motor with neodymium magnets”.

Control Technologies
FANUC Servo control technology (SERVO HRV Control), whichhas plenty of achievements on feed axis of machine tool, with functions for high precision or avoiding mechanical resonance and so on, is applied for Synchronous built-in servo motor system also.In case of driving one axis by plural motors, sometimes stability is not secured because of interference between motors. Stabilizing functions to prevent interference between axes, are prepared in order to secure stability.
SERVO HRV Control
Achieving high precision by combination of Synchronous built-in servo motor. Best suited to cam grinding or gear cutting machine.・Sufficient Learning time of maximum 262 seconds and maximum 24 Learning profiles are available. (Suited to cam grinding machine)・The combination of Learning Control and EGB control minimized synchronous error. (Suited to gear cutting machine)
