Three-phase AC servo motors are widely used, but through long-term operation, various faults may occur. Timely identification of the fault cause and corresponding treatment are important tasks to prevent the fault from expanding and ensure the normal operation of the equipment.
Three-phase AC servo motors are widely used, but through long-term operation, various faults may occur. Promptly identifying the cause of a fault and carrying out corresponding treatment is an important task to prevent the fault from expanding and ensure the normal operation of the equipment.
Firstly, after power is applied, the motor cannot rotate, but there is no abnormal noise, no strange smell, and no smoke.
1. Fault causes: ① Power supply is not connected (at least two phases are not connected); ② Fuse blown (at least two phase fuses blown); ③ Overcurrent relay setting is too small; ④ Control equipment wiring error.
2. Troubleshooting: ① Check the power circuit switch, fuse, and junction box for open circuits and repair them; ② Check the fuse type and the reason for the fuse blowing, then replace with a new fuse; ③ Adjust the relay's setting value with the motor; ④ Correct the wiring.

Analysis of Causes for AC Servo Motor Failure
Three-phase AC servo motors are widely used, but through long-term operation, various faults may occur. Timely identification of the fault cause and corresponding treatment are important tasks to prevent the fault from expanding and ensure the normal operation of the equipment.
The working principle of a servo motor is relatively simple, but its efficiency is relatively high. The servo circuit is built into the motor unit, which uses a flexible shaft usually equipped with gears.
Single-layer winding three-phase asynchronous motor
A single-layer winding is one where only one active side of a coil is embedded in each stator slot, so the total number of coils is only half of the total number of motor slots.
Starting of three-phase asynchronous motor
However, when a three-phase asynchronous motor starts directly, the current can reach 6-7 times the rated current, which has a significant impact on the power grid, especially for high-power motors.
Striped appearance on the outer surface of motor housing extruded profiles
Hollow aluminum alloy profiles are produced using the flat flow split combination die extrusion process. This process presents a relatively increased difficulty in profile production, as the metal goes through a diversion and welding joint process, therefore, hollow profiles have weld lines.
The motor casing is a main component of the electric submersible pump motor.
The motor casing is a main component of the electric submersible pump motor, and its machining accuracy directly affects the quality of the electric submersible pump. Due to the motor casing's thickness being greater than its radius during turning with clamping holes, it is prone to oval deformation. The deformation generally ranges from 0.03 to 0.10 millimeters, which cannot meet user requirements. If this problem is not resolved, it will lead to significant economic losses in producing qualified products.
