The electric spindle of Horizontal lathe has the advantages of compact structure, light weight, low inertia, low noise and fast response. The servo spindle of the lathe machine has high speed and high power, which simplifies the design of the machine tool and is easy to realize the spindle positioning. It is an ideal structure in high-speed spindle units. The electric spindle bearing adopts high-speed bearing technology, which is wear-resistant and heat-resistant, and its service life is several times that of traditional bearings. So how should we solve the phenomenon that the electro-spindle does not run after starting up and stops after running for a few seconds after starting up? The following OTURN will take you to see the reasons and solutions!
The electro-spindle does not run after the machine is turned on.
Reason 1. There is no output voltage parameter setting error of the variable frequency power supply.
Elimination method: Check the inverter setting method and whether the three-phase voltage is the same.
Reason 2. The motor plug is not inserted properly.
Remedy: Check the power plug and connection.
Reason 3. The plug is not soldered well and the contact is not good.
Remedy: Check the power plug and connection.
Reason 4. The stator wire wrap is damaged.
Remedy: replace the wire package.
After starting the machine, it will run for a few seconds and stop.
Reason 1. The startup time is short.
Remedy: Extend the acceleration time of the inverter.
Reason 2. The coil water inlet insulation is low.
Remedy: Dry the coil.
Reason 3. The motor lacks phase operation and causes overcurrent to protect the power outage.
Remedy: Check the motor connection.
The above content is the reason and solution for the electric spindle of CNC lathe not to run after starting up and shutting down after running. I hope it can help you!
