Servomotor with integrated controller CM3-17L50A

hybrid stepperDC24 V

Overview
COOL MUSCLE 3 is an integrated stepper-based motion system combining motor, driver, controller and encoder. By focusing on essential motor-control functions, it delivers a simplified, cost-efficient solution for high-precision motion control in compact industrial equipment.

Achieve servo equivalent performance using a stepper motor
Muscle's proprietary control technology eliminates common stepper drawbacks such as step-out, excessive heat, high acceleration/deceleration issues and noise, enabling performance comparable to a servo motor. The result is high-precision motion control with a simple configuration and lower system cost.

Contributes to space and wiring saving
Driver, controller and encoder are integrated into the motor rear, significantly reducing wiring and overall footprint. Recommended for desktop devices, mobile equipment and small-size machinery where control panel space is limited.

3 control types

• Direct Type (Communication Control Type): Direct operation via RS232C serial communication. Positioning by setting position, speed and acceleration. Up to 32 Motion Data points can be stored and executed.
• I/O Type: Up to 8 Motion Data points can be stored in CM3. Motion Data selection and execution are performed via PLC I/O signals.
• Pulse Type: Control CM3 using pulse signals from a PLC. CM3 provides ABZ output to allow replacement without modifying existing systems.

Stepper Motors Comparison

• Torque (low speed range): High torque is available at low speeds without step-out risk, enabling smaller motors for heavy loads and precise motion in constrained spaces.
• Maximum Speed: Achieves high-speed control comparable to servo motors.
• Speed Stability: Low speed ripple at continuous speeds improves measurement accuracy and constant-speed applications.
• Responsiveness: High acceleration and deceleration capability reduces cycle times and increases throughput.
• Loudness / Vibration: Vector-like control produces smooth motion with reduced noise and vibration—suitable for image inspection and noise-sensitive equipment.
• Current Level / Temperature: Load-adaptive current control minimizes consumption and heat generation, enabling long-term continuous operation and energy savings for battery-powered devices such as AGVs.

Higher performance than servo motor
Unlike typical servos that must operate below rated continuous torque (approximately 30% of peak for continuous use), COOL MUSCLE 3 can sustain high torque during continuous operation, providing greater torque output from a smaller motor at low speed ranges.
