Item Type: MotorMaterial: Brass, Copper, Steel, CarbonShaft Length: Approx. 10mm/0.4inShaft Diameter: Approx. 3mm/0.1in(D Shaped Shaft)Operating Voltage: DC 12VUses: Can be used in smart toys, analog robots, electronic locks and other fieldsPackage List1 x Motor1. When you use the motor, there should be no binding objects. For example, the adhesive should not be injected into the bearing through the rotating bearing, which will hinder the operation of the motor.2. The rotation of the shaft may have an opposite effect on the life of the motor. In order to extend the life, please check whether your load is in accordance with the regulations, and it is not allowed to be overloaded or there are items that hinder the rotation of the shaft.3. Manufactured into an eccentric heavy radiation load, which is harmful to the life of the motor.4. Do not store in surrounding high temperature or extreme humidity, and do not place it in corrosive gas, which will reduce the effect of the motor.1The gear is made of high quality metal material, which has the characteristics of impact resistance, durability, low noise, etc. 2The rotor adopts pure copper coil, with small electric group, strong conductivity, low heat generation, stable output, low loss and long life. 33 layers of high density molecular paint drip coating, effectively insulate dust and high temperature resistance 4The carbon brush bearing reduces the friction between the roller and the bearing, is not easy to get hot, high load resistance, and is not easy to fade and rust. 5This DC metal motor can be used in smart toys, analog robots, electronic locks and other fields.
