## Description

Rated Voltage: DC 12V Reduction Ratio: 1:634 No-Load Speed: 3RPM Rated Torque: 12Kg.cm Rated Current: 130/150mA(Positive Rotation / Negative Rotation) Error: ±10% D Shaped Output Shaft Size: 8*15mm (0.31" x 0.59") (D*L) Gearbox Size: 58.1 x 40.11 x 36mm (2.29" x 1.58" x 1.42”) (L*W*H) Motor Size: 31 x 57.2mm (1.22" x 2.25") (D*L) Mounting Hole Size: M4 (not included) Main Material: Metal, Electronic component Wire Length : 20cm Packages: - 1 x Worm Gear Motor What does motor torque mean? The standard torque of the motor is 10kg.cm. If the belt wheel is used for transmission, the belt wheel has a radius of 1cm, and the output tension of the belt is 10kg. If the belt radius is 2cm, the output tension of the belt is 5kg, and so on. PLEASE NOTE: 1.Use tolerance: Pay attention to the use of voltage and current range, otherwise the motor performance and motor life will decline. 2.Handling motors: Gently, as far as possible the use of motor shell part. 3.Motor wiring: Red lead to the positive electrode, black lead to the negative pole, if reversed, the motor rotation in the opposite direction. 4.Overload: As far as possible within the specified load range, prohibit motor blocking or close to the stall state for too long time to runs. Otherwise, the motor will burn out. 5.Motor storage: -- Storage temperature: 0℃ - 40℃; -- Storage humidity: 15% -90% RH; -- Avoid placing in high temperature, high humidity and corrosive gases. 6.Motor use temperature: 0℃ - 70℃

A: It all depends on load...if you are worried you could ramp your starts and stops.
