Challenge to low-cost innovation
Integrated AC Servo System
COOL MUSCLE 3 is the Integrated Servo System equipped with devices that are required for motor control such as a driver and encoder. By eliminating complex functions and reducing them to the essentials, COOL MUSCLE 3 can offer a simpler and more affordable solution.
Achieve servo equivalent performance using a stepper motor
COOL MUSCLE 3 eliminates stepper motor’s particular weak points such as step-out, heat generation, high acceleration / deceleration, noise and so by Muscle's original control technology, and realizes performance comparable to servo motor. High-precision motion control can be achieved at low cost with a simple configuration.
Contributes to space and wiring saving
Built-in driver, controller, and encoder in the back of a motor. Wirings and the total volume can be significantly reduced.
Especially recommended for desktop devices, mobile devices, and small size equipment where it is difficult to secure control panel space.
3 control types
Direct Type (Communication Control Type)
You can operate the motor directly by sending and receiving commands via RS232C serial communication.
Positioning to any position is possible by simple settings such as position, speed, and acceleration.
Up to 32 points of Motion Data can be stored and executed.
Up to 8 points of Motion Data can be saved in CM3.
Motion Data can be selected and executed by signals from I/O port on PLC.
Control CM3 by pulse signal from PLC.
CM3 has an ABZ output function so it can be replaced without changing an existing system.
Higher performance than servo motor
Servo motor must be used within the rated torque (torque of about 30% of the maximum torque) when operating servo motor continuously. Since COOL MUSCLE 3 can keep producing the maximum torque even during continuous operation, it is possible to output a large torque from a small size motor at a lower speed range.
Stepper Motors Comparison
- Torque (low speed range)
- Maximum Speed
- Speed Stability
- Current Level
High torque output is possible even at low speeds without risk of step-out
