Advantages and maintenance of high-efficiency and energy-saving motors

The editor has previously introduced the principles and characteristics of high-efficiency and energy-saving motors. It can be seen that the principle of this motor is relatively complex and has many popular features. It is precisely because of its many features that this motor is favored by various industries. So what are the advantages and maintenance of high-efficiency and energy-saving motors? Please read the detailed introduction below!

maintenance work:

In the process of using high-efficiency and energy-saving motors, some bad phenomena will inevitably occur, so we must perform necessary maintenance on it. Although these problems will not occur with every user's energy-saving motor, many problems are often caused by users' neglect during use. Therefore, no matter whether the user's high-efficiency and energy-saving motor has the above problems, regular maintenance can ensure better operation of this equipment.

Ensuring the normal use of high-efficiency and energy-saving motors is a basic requirement for them. Although we cannot fundamentally prevent the occurrence of energy-saving motor failures, once some defects appear during the use of this motor, it will have an impact on its own use. In addition, it can also be of great assistance.

During the operation of the energy-saving motor, its own margin is relatively large. This is a relatively common problem, and energy-saving motors often vibrate greatly under high-speed, low-load operating conditions, and the on-site noise is also ly strong, and the working environment is very harsh.

When the baffle is adjusted below 10%, excessive negative pressure will cause pipeline surge and endanger the normal operation of the equipment. No matter what the environment, personal safety and equipment safety are ly important.

Under the conditions of the power grid capacity in the factory, the inertia torque output of the energy-saving motor is large. When starting directly, the starting current of the motor is very high, which may cause the high-voltage power supply line protection to operate, causing the motor to be unable to start continuously. At this time, users need to pay full attention to the current and rated voltage of the power supply when starting the energy-saving motor, so that the device can start in a normal environment.

When the motor is started, the power consumption per start is approximately the same as one day's power consumption during normal operation. During normal operation, the power loss of high-efficiency and energy-saving motors is relatively serious. When the baffle opening is below 50%, the wind pressure on both sides of the baffle is relatively large, and it is easy to cause great throttling loss and wind pressure loss. This problem is very complex to solve and requires the user to have some specialized knowledge about electricity.

advantage:

1. Direct start, asynchronous motor can be replaced;

2. The earth permanent magnet high-efficiency energy-saving motor itself can save more than 3% of electric energy than ordinary motors;

3. The power factor of the motor is generally higher than 0.90, which improves the quality factor of the power grid without adding a power factor compensator;

4. Adding a driver can realize soft start, soft stop and stepless speed regulation, and the power saving effect can be further improved.
