    Tips: 1.5kW CNC Spindle Motor Using Case

    A customer inquired that his engraving machine has been purchased for 10 years, and it has been used normally. However, during the recent use, the 1.5kW spindle motor of the engraving machine stopped suddenly and the VFD displayed ERR 01. Sometimes the motor is energized with a buzzing sound, but it does not rotate. After the situation occurred, the client did not understand the reason, so consulted ATO. Below is a summary of the reasons and solutions for the spindle of the CNC engraving machine to stop, for the reference of the majority of users:

    1. The three-wire cable plug-in connecting the spindle motor to the inverter is disconnected. Solution: Reconnect or reconnect and try again.

    2. The lead wire in the spindle motor of the engraving machine is open welding. Confirmation method: Measure the resistance between the three cores of the spindle motor socket with a multimeter. Solution: Remove the socket and re-solder the open wire.

    3. The three-wire cable connecting the spindle motor to the frequency inverter is disconnected. Confirmation method: Measure the resistance between the plugs at both ends of the cable with a multimeter. Solution: Connect the broken wire or replace the wire.

    Safety Tips for Using ATO CNC Spindle Motors

    1. The electric spindle motor and VFD shall be suitable with each other. The specifications and parameter settings of the VFD shall match the nominal parameters of the spindle motor, and it will burn the spindle motor if the settings are not correct.

    2. Before using water-cooled spindle motor, it shall ensure that cooling cycle system works normally and the running under no cooling conditions is prohibited. The volume of cooling water is calculated as per 1 liter/minute, the minimum flow of cooling water is not less than 5 liter/minute, cooling water pipe and the nozzle shall be connected reliably and there is no leakage.

    3. The cooling liquid shall be clean and free of grease and the temperature shall be within 5-30℃. The cooling medium shall carry out force cooling when the ambient temperature is higher than 30℃. The precision lathe requires the cooling liquid with a constant temperature of 20 +/-2℃.

    4. During storage and transport of the spindle motor, the status of high-speed grease inside the bearing will change. The user shall run it at a low speed first by starting from the lowest speed of the spindle motor for 30 minutes and then 20 minutes for every 3000 rounds. Otherwise there will have abnormal sound, noise, heat and other phenomena, which will affect the bearing life if the spindle motor is started directly at a high speed. During long term storage, the spindle motor shall run (at low speed) for 15-30 minutes once a week at last.

    5. Collet, nut and inner taper hole shall be washed clean when installing blades on the spindle motor in order to avoid any impact on the precision. The blade handle shall be inserted into the collet more than 15mm.

    6. For daily machining, the spindle motor shall be warmed up, run for 15-20 minutes when the machining speed is reached and then performs precise machining. It is better to stop the spindle motor for two hours every day in order to recover its mechanical fatigue and prolong its life time.

    7. No knocking the end cover of the spindle motor. No hammering the collet and blade head when removing blades. No shocking or colliding during transport, storage and using, especially the end of the spindle motor.

    8. The spindle motor shall run in designated direction.

    9. The spindle motor shall be installed and fixed according to the relevant drawings and instructions.

    10. The temperature shall be within 22-25℃ if water cooling machine is used.

    11. The spindle motor adopts vapor lock and the gas source shall not be used until it has passed oil-water separator and dry filter. The air pressure is 0.2-0.25Mpa and the filtering precision is 5μm, otherwise there will cause damages to the bearing.

    I am interested in your spindle motor.
    For your ATO-SPINDLE-800 spindle. Do power connectors and brackets come with the spindle?

    ATO Responded
    Yes, the power connector and bracket can be included on the ATO-SPINDLE-800 spindle motor.
    High speed cnc spindle motor
    I ordered the 1.5kW air cooled spindle motor - shipping was quick, no complaints there. The spindle itself seems like decent quality. I will still order from him.
