◆Two speed control modes: no PG vector control (SVC), V/F control

◆ No PG vector control (SVC): starting torque 0.5Hz up to 150%

◆ 8-stage simple PLC function, multi-speed control and PID control

◆ Support multiple frequency settings: digital setting, analog setting, PID setting, RS485 communication setting

◆ I/O terminals can be freely programmed to combine multiple working modes according to user needs.

◆ With jump frequency control function, it can effectively suppress mechanical resonance and make the system more stable and reliable.

◆ With instantaneous power-down retention function, it can avoid the impact of production due to instantaneous power failure

◆ With over torque and under torque detection

◆ Automatic voltage adjustment function to effectively solve the low frequency oscillation problem of high power motor

◆ Provide a variety of fault protection functions: over-current, over-voltage, under-voltage, over-heat, overload, lack of equal real-time monitoring and protection to ensure safe operation

◆ Built-in reactor with inverter above 37kW, which improves the power factor of the input side and improves the efficiency and stability of the whole machine.

◆ 0.75~15kW built-in braking unit.

DO NOT set up the inverter by yourself if you don't know how to, or it will make both the spindle and inverter burn easily.

Please contact us, we have manuals, videos and pictures to help you.






Diameter:  65mm

Material: Cast Aluminium



  • Compared with the aluminium profile fixture,the accuracy is much higher , and it is hard to deform.

  • Inner wall is very smooth,  outer walls is sandblasted, relatively fine uniform,  but not very smooth.

  • Cast aluminium fixture is much heavier than aluminium profile fixture.



  • Cast aluminium fixture is high quality aluminium which is casting with a special manufacturing process ,compared with ordinary aluminium ,This product has toughness, strong shock resistance, high hardness and strong antioxidant activity. 



  • Cast aluminium fixture is mainly used for fixation of ancillary products, thereby ensuring the verticality of balancing and ancillary products, ancillary products to improve running accuracy, reduce noise, reduce the accumulated error.



  • Spindle working environment temperature is usually -10  ~ 40 .
  • Before installing the first electric spindle axis head turned by hand, should feel flexible, non-blocking phenomenon.



  • Spindle in the preservation and transportation, high-speed grease inside the bearing state will change, customers should be running at low speed for 30 minutes. 3000 rpm and then follow the poor increase, run 20 minutes each. Spindle and the inverter should be working together. The inverter's specifications and parameter settings need match spindles parameter.(Because of high-speed grease inside the bearing state will change,when you get the spindle, maybe the noise sounds not normal.Please run it 30 minutes or even more, the noise will be normal.)

  • Connect the inverter spindle, three-phase inverter power cord should be soldered in the plug 1 (U), 2 (V), 3 (W) feet, 4 feet for the ground. After the power is turned on, to observe whether the spindle rotation axis indicates the direction consistent. If inconsistency should be immediately shut down, replace the inverter and spindle connected two wires of three-phase power supply.

  • During normal operation, air-cooled spindle often encounter the phenomenon of heat, always check whether the air-cooled spindle housing and duct clogging dust.If clogging dust, to promptly clean up. If you do not clean up, it is easily to make the spindle burned.

  • Every day before using the spindle must be running at low speed for 15-20 minutes. Clamping the cutters to spindle, collet nuts ,collets,cutters must be clean enough. Shank inserted into the collet must be greater than 15mm.


  • Spindle frequency power supply connected rated voltage, frequency should be consistent with the technical parameters of the electro-spindle, spindle speed can be adjusted to change the frequency, and voltage is proportional to the change. 

  • Spindle being not used,spindle appearance should be oiled. Plus the shaft protection device, put in a dry place. 

  • To replace the spindle bearings, certain professional and technical personnel should be replaced.Supporting special tools, bearings should be replaced fully cleaned without removing the stator coils.
