Item Type: Motor Material: Copper, Alloy Shaft Length: Approx. 15.5mm/0.6in Shaft Diameter: Approx. 6mm/0.2in Diameter D Shaped Shaft Motor Diameter: Approx. 37mm/1.5in Uses: Suitable for robots, mechanical equipment, smart machines, power window, power doors, automatic rotating equipment, pan tilts, etc. Package List 1 x Motor 1. Make sure that the voltage of the motor is correct before use. If it is a DC motor, confirm whether the power supply current is sufficient.2. It cannot be used with overload. The reason for overload is mainly divided into two parts: Torsion and shaft force. The load torsion cannot exceed the rated torsion of the motor. The shaft force cannot exceed the axial and radial allowable force of the shaft. After the load is loaded, the measured current of the motor cannot exceed the rated current. Generally, the motor must be equipped with a fuse to avoid overloading the motor.3. Do not store or operate in a high temperature or humid environment, and do not place it in corrosive gas, which will reduce the effect of the motor. 1Starting helical gear structure reduces load noise, high torsion, and stable performance. Small size of the motor teeth and high accuracy. 2After grinding, the gear is heat treated, with good wear resistance, long life and high performance. 3The shell is made of all metal materials, which are not rusty, not easy to corrode, easy to install and long service life. 4Brushless accuracy control, with forward and reverse tuning, FG signal feedback, PMW pulse width speed regulation (maximum life is 10000H). 5Suitable for robots, mechanical equipment, smart machines, power window, power doors, automatic rotating equipment, pan tilts, etc.
