Some Advantages with our Spindle Motor

• Bearing is P4 grade, 2x7005C P4 DB ( Ceramic ball bearings ) & 2x7203C P4 DT
• The front-end bearings are ceramic ball bearings, increasing the spindle life.
• 3.5kw ER20 air-cooled spindle, the collet nut range from 1mm to 13mm.
• High precision, runout off less than 0.01mm.Coaxial degree less than 0.0025mm

Structural features :

• High-speed electric main bearings used in all C class high-speed angular contact ball bearings, axial pre-load feature, improved support stiffness, and live spindle grinding accuracy under high-speed rotation. 
• Spindle speed according to different uses can be high-speed grease and oil mist lubrication two ways. 
• Spindle speed rotation temperature rise caused by the use of a coolant circulation system was eliminated.

VFD Parameters

• Inverter Number: Fuling 220v 3.7kw
• Input Voltage: 220v(+/-15%) 
• Input Frequency: 50/60Hz
• Input Phase: 1 or 3 phase
• Output Voltage: 220vAC
• Output Frequency: 0-1000 Hz
• Output Current:15A
• Output Phase: 3 phase  

Some Advantages of our VFD Control

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