Item Type: Worm Gear Motor Material: Iron, Plastic, Zinc Alloy Motor Parameters Voltage: DC 24V Power Range: DC 12-30V Speed Governor Technical Parameters Model: CCM2 Working Voltage: DC 10V-30V Control Power: 12V x 3A = 36W, 24V x 3A = 72W; Greater than 24V, Maximum 120W Rated Current: 3A Maximum Current: 5A PWM Pulse Width Adjustment Range: 5%-95% Potentiometer: Resistance Value B10K, Wire Length Approx. 20cm / 7.9in, Opening Approx. 8mm / 0.3in Output Voltage: Approximately 0-100% of Input Voltage Speed Governor Size: Approx. 74 x 47 x 28mm / 2.9 x 1.9 x 1.1in The potentiometer is used for speed regulation. Forward and reverse switches are used to control forward, reverse, and stop functions. Features: 1. High-precision all-metal gears provide low noise operation. Zinc alloy die-cast housing with stainless iron hardened output shaft. 2. Turbine reduction design with all-metal gears. Compatible with governor for speed control. Motor supports forward and reverse rotation. 3. Motor includes power-off self-locking function. Maximum gear load capacity is approximately 30kg. 4. Worm gear motor offers low noise, high torque, and precision craftsmanship to extend service life. 5. Suitable for electronic locks, range hoods, display stands, robots, smart devices, barbecue machines, nesting machines, and entertainment equipment. Speed Controller Notes: 1. The DC motor speed controller input is DC only. Do not connect directly to AC power (such as household 220V AC), as this will damage the unit. 2. Do not reverse the positive and negative terminals of the DC power supply, as this may damage the speed controller. 3. Motor rotation direction can be forward or reverse. If rotation direction does not match expectation, adjust by changing wire sequence. 4. The potentiometer knob adjusts the duty cycle of the controller output, thereby controlling motor speed.
