How To Maintain The Stepper Motor Of Computerized Embroidery Machine

In case of failure, the general practice is to replace the control board, that is, send the defective control board to the manufacturer or the Distribution Department, and then send it back after repair. It will take a lot of time and inconvenience to the enterprise, and it will seriously affect the production.

In order to reduce the trouble, the author can make a maintenance test stand automatically to solve the above problems.

The maintenance test bench is composed of a power supply, a control board signal source, a stepper motor plate being repaired and a five phase stepper motor.

Among them, the power supply is made up of high voltage, low voltage, protection circuit, adjusting the lower bending needle, so that the downward bending needle tip is about 3 millimeters away from the left needle center line.

High voltage delay and high voltage discharge circuit.

The source of the control board is generated.

Drive power supply signal, forward, reverse, start, stop, signal indication, turn the downward bending needle to the far left.

The main application of design and clothing stores, but the early software effect is limited due to the limitations of two dimensions and complex operation. However, in recent years, scientific and technological enterprises in this direction are increasingly looking forward to the popularization and application of ideal software.

The current limiting signal and fault signal are composed.

Generally speaking, the two-phase motor has large step angle and high speed characteristics, but there is a low velocity vibration region.

The five phase motor has small stepping angle and low speed operation. When the bending needle tip coincides with the neutral line of the left needle, the needle bar height is adjusted, so that the downward bending tip is 1.5 to 1.8 millimeters away from the upper edge of the needle hole on the left side.

Therefore, the accuracy of motor operation is higher.

If the machine is running at low speed (usually less than 600 rpm), five phase motors can be used.

If the motor has high speed performance and there is not much demand for accuracy and smoothness, the two-phase motor with lower cost can be selected.

In addition, the torque of the five phase motor is usually more than 2 nm, and the two-phase motor is usually used for small torque applications.

When there is a problem of low speed stability, subdivision driver can be used to solve it.

The adjustment method described from the letter can not be fully understood yet. The author suggests that it should be carried out according to the requirements and methods.
