Why does the vibration motor emit smoke?

Usually, during the operation of a vibration motor, due to inadequate maintenance and upkeep of the motor, or insufficient voltage stability, smoke may occur unexpectedly. There are also some reasons that cause smoke from the vibration motor. How can these reasons be solved? In such cases, please do not panic, cut off the power supply first, identify the cause, and take corresponding measures, Next, we will provide a detailed introduction to how to address such issues:

Firstly, let's understand the reasons for such problems:

1. The vibration motor is overloaded or starts frequently during operation;

2. Broken cage rotor bars inside the vibration motor;

3. The fan of the vibrating motor malfunctioned, resulting in poor ventilation;

4. The high power voltage of the vibration motor greatly increases the heating of the iron core;

5. The vibration motor is out of phase during operation and operates in two phases. The meaning of phase loss is the lack of a live wire. If a vibrating motor lacks a live wire due to various reasons, it will rotate unevenly and slowly during the operation of the vibrating motor, and generate heat. If the vibrating motor does not stop the machine in a timely manner at this time, it will produce symptoms of smoking or burning of the vibrating motor. Next, we need to find solutions to these problems: In response to the five possible situations that may cause vibration motors to smoke, we will explain how to respond:

1. We need to pay attention to this point ourselves. When reducing the load of the vibration motor, it should be controlled to start according to the specified number of times;

2. Check and eliminate rotor winding faults of vibration motors;

3. Inspect, repair, and replace the fan of the vibration motor

4. At this point, we can reduce the power voltage of the vibration motor (such as adjusting the tap of the power transformer) and correct the connection method. A vibration motor is a set of adjustable eccentric blocks installed at both ends of the rotor shaft, which utilizes the centrifugal force generated by the high-speed rotation of the shaft and eccentric blocks to obtain the excitation force. The vibration frequency range of a vibration motor is large, and only when the excitation force and power are properly matched can mechanical noise be reduced. There are six classifications for vibration motors, including classification based on starting and operating modes, and classification based on operating speed.

5. The solution is to activate the thermal relay protection. In case of phase loss, the contactor can protect the two phases from self opening during phase loss, and the thermal relay can cut off the contactor during overcurrent. There are many manufacturing materials for warehouse wall vibrators, including carbon steel, cast iron, aluminum alloy, bronze, stainless steel, and extruded aluminum. For applications in special environments, such as the pharmaceutical industry, the shell can be made of aluminum or stainless steel. Its vibration frequency and intensity can be precisely controlled (stepless adjustment) by adjusting the flow rate and pressure of compressed air. When using a concrete mixer to mix and pour concrete components, the warehouse wall vibrator must remove bubbles and perform compaction to ensure a dense bonding of the concrete, eliminate honeycomb and pitted surfaces, and improve its strength to ensure the quality of the concrete components. A concrete vibrator is a device that uses power to generate frequent vibrations through a certain device as a source of vibration, and transmits this vibration to the concrete to vibrate and compact it.
