Characteristics of grinding electric spindle

The electric spindle is composed of a shellless motor, a spindle bearing, a spindle unit, a housing, a drive module and a cooling device. The rotor of the motor is integrated with the main shaft by press-fitting method, and the main shaft is supported by front and rear bearings. The stator of the motor is installed in the housing of the spindle unit through a cooling jacket. The speed change of the spindle is controlled by the spindle drive module, while the temperature rise within the spindle unit is limited by the cooling device. A speed and angular displacement sensor is installed at the rear end of the spindle, and the inner taper hole and end face at the front end are used to install cutting tools
