## Description

Rated Voltage: DC 12V Reduction Ratio: 1:634 No-Load Speed: 10RPM Rated Torque: 40Kg.cm Rated Current: 1400/1280mA (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℃

Review: Very slow with a lot of power - I got the 10rpm one they have a lot of power well made. Mine were only tapped on shaft side. I just tapped out other side myself with 4mm tap.
Review: Update: I have discovered in real world application that the 250RPM motor is stalling despite the production testing success. Not the fault of the motor though. I didn’t calculate the required torque to extended the solar panels. Going to replace it with the 110RPM version or even the 60RPM to get the required torque, albeit at a slower extension/retraction speed. I am surprised that forward/reverse directions have different speeds and torques, although the specs do mention that. Used this on a retractable antenna for my RV among other projects. I love this motor, have used 5 of these. It is high torque, works well in this application. My only complaint: WISH THE SHAFT WAS LONGER. For outdoor use, I place it inside a motor shroud. Problem is there's not much shaft left to protrude for the shaft coupling to grab. Typically I drill a detent hole in the flat part of shaft and mount a set screw in the coupling to grab it. Haven't found a shaft coupling yet specifically for the 8mm D shaft that the motor has.

## Features

- 【High Torque & Lower Noise】: Long carbon brush high life, high precision gear design, small size, high torque, low noise, high efficiency.
- 【Positive-Negative Rotation】: This type is miniature High Torque Electric Worm Gear DC Motor, which can change shaft rotation direction while the wiring positive andnegative be changed.
- 【Self-Locking】: Turbo worm geared motor with self-lock, that is, in the case of motor without electric, the output axis is fixed, self-lock.
- 【Versatile】: The reducer output shaft arranged vertically with the motor shaft, whole motor output is relatively short,can be widely used in various of occasions that require special installation size.
- 【Application】: Boat, Car, Fan, Home Appliance, BBQ, Machinery and equipment, automation instruments, electric curtain, stage lighting, counter, faucet, safe, wet towel dispenser, vending machines, automatic monitoring and other modern art.
