[Specifications] This DC 12V motor has 8 mm shaft (15mm long), we offer different speed motor, please choose the right one for you before purchasing. The shell of the geared motor is made of all metal, which is wear resistant and not easy to rust, and has good thermal conductivity. [High Quality] The shell of the geared motor is made of metal, which is wear resistant and not easy to rusty, and has good thermal conductivity. After the gear is ground, heat treated and filled with imported lubricating oil, has low friction coefficient and high load carrying capacity. [Wide Range of Applications] The DC geared motor with driver has strong torsion, suitable for curtain machines, billboards, window openers, etc. With brass turbine worm and double ball bearings, the noise generated by the motor running is small. [Control] The driver use PWM to control speed, and use CW and CCW switch to control forward, reverse and stop. The motor adopts stainless steel output shaft with a diameter of 8mm, a high accuracy structure, and runs smoothly and silently. [Stable] After the gear is ground, heat treated and filled with imported lubricating oil, has low friction coefficient and high load carrying capacity. Specification: Item Type: Geared Motor Model: 5840-31ZY Working Voltage: 12V Shaft Length: Approx. 15mm / 0.6in Shaft Diameter: Approx. 8mm / 0.3in DC motor regulator CW and CCW control Model: CCM2 Working Voltage: DC 10V-30V Control Power: 12V x 3A=36W, 24V x 3A=72W, 24V, maximum 120W Rated Current: 3A Maximum Current: 5A PWM Pulse Width Adjustment Range: 5%-95% Potentiometer: Resistance value B10K, wire length is approx. 20cm / 7.9in, opening approx. 8mm / 0.3in Output Voltage: About 0-100% of the input voltage Drive: Approx. 74 x 47 x 28mm / 2.9 x 1.9 x 1.1in Potentiometer is used for speed regulation Package List: 1 x Motor 1 x Governor 1 x CW and CCW Switch 1 x Knob Cap 1 x Washer 1 x Bracket 4 x Mounting Screw Note: 1. When soldering is required on the positive and negative motor terminals of the power supply, the temperature of the soldering iron is 34040, and the heating time is less than 3s. 2. The maximum bearing capacity of the gear is 70KG, blocking is forbidden, and the motor may be burnt if it is blocked for a long time. 3. When installing the motor, if the screw is too long, it will cause contact between the motor and the rotor, thereby affecting the characteristics.
