Description When you use the motor, there should be no binding objects, such as the adhesive should not be injected into the bearing through the rotating bearing, which will hinder the operation of the motor. The rotation of the shaft may have the opposite effect on the lifespan of the motor. In order to extend the lifespan, please check if your load is in accordance with regulations and do not overload or hang objects that hinder rotation on the shaft end Manufacturing an eccentric heavy radiation load can harm the lifespan of the motor. Do not store in high temperatures or extreme humidity around, nor do you place it in corrosive gas, as it may reduce the effectiveness of the motor. Do not operate the motor in the surrounding high temperature and humidity. type: Brushed gear motor 372 Rpm / 63 Rpm / 17 Rpm / 2386 Rpm Standard Operating Conditions: Rated Voltage: 6v.
