the AC Servo System that is comibined with a driver, controller and encoder.
Those are necessary devices to control servo motor.
COOL MUSCLE is a precisehigh performance motor that can be controlled easily and presicely even if you don't have a knowledge of conventional servo motor.

Small and Simple by "Integration"

All devices that are necessary for conventional motor control are integrated in COOL MUSCLE. External control devices and complicated settings and wirings are not necessary any more.
You can simply experience a precise and high performance motor control.
Benefit of Integrated COOL MUSCLE
Wiring & Space Savings
Integrated COOL MUSCLE contributes to wiring and space savings only by plugging a cable to PC or PLC.
It is very simple without general complicated wirings. It eliminates the time for assembly and maintenance.
Servo Control at Affordable Pricing
COOL MUSCLE's servo control is achieved by mounting an encoder to a stepper motor. Expensive and complicated servo control can be realized easily and simply.
Many Accomplishments
COOL MUSCLE has been used in millions of applications. You can use COOL MUSCLE with relief that has been used in medical, semi-conductor, entertainment and more applications.

Utility Software CWL
User interface that you can control COOL MUSCLE intuitively. You can easily set parameters, data and monitor COOL MUSCLE from CWL.。
High Performance
COOL MUSCLE that uses a stepper motor produces high torque at low speed.
MUSCLE's own control by high resolution encoder benefits energy saving, lower heat generation and smooth rotation.
Resolution (ppr)
High resolution by MUSCLE'S own encorder system
Current (mA)
Reduce power consumption Energy saving
Noise (dB)
Quiet and Smooth rotation
Temperature (℃)
Only necessary currrent will be drawn Energy saving and low heat generation
※ Based on internal investigation
Faster, Quietter and More Precise
Full-Closed Loop
COOL MUSCLE never miss its position and stalls because of its full-closed loop control.
Vector Control
COOL MUSCLE that uses vector control realizes smooth rotation even at low speed range. It contributes to lowering vibration of machine.
Super Slow Speed
COOL MUSCLE embeds 50,000 resolution encoder and it allows super slow speed control at minimum 0.012RPM. It realizes precise control from low to high speed.
