1. This spindle motor should be used with the inverter. The specifications and parameters of the inverter should match the rated parameters of the spindle motor. If the settings are incorrect, the spindle motor will be burned.
2. Before the use of this spindle, users must ensure the cooling circulation system of the spindle is working normally, and it is strictly prohibited to run the motor without cooling water.
3.During the storage and transportation of the spindle motor, the state of the high-speed grease inside the bearing will change; hence, customers should run the spindle motor at a low speed before its use.
4. The advantages of HQD 5.5KW stone bullet water-cooled spindle motor (constant torque): Regardless of spindle motor's speed, as long as the parameters are set in the inverter, the torque can be unchanged and the working efficiency is higher. The spindle motor shell is made of steel that is waterproof and durable. The use of ceramic ball bearings increases the service life of the spindle motor and can process metal moulds. The rotor uses a high-quality steel rotor, and the cutting force is stronger. The coil uses an extended coil to ensure more power.
