Today we are going to carry out vibration motor performance test. This is 220V input. (Force is 30kg) vibration motor. The rated current and power are 0.1A and 30W respectively. We are able to open one side of cover. Now we can see, adjustable eccentric block is connected end of rotor shaft. Both two sides of the nut are same construct. The eccentric block is used to obtain the exciting force. The combination of the specific designed motor and the eccentric block enable the motor to rotate.

The brushless DC vibration motor consists of a motor body and a driver and is a typical mechanization product. The star winding of the motor is mostly made into a three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. A magnetized permanent magnet is attached to the rotor of the motor. In order to detect the polarity of the motor rotor, a position sensor is installed in the motor. The driver consists of power electronic devices and integrated circuits.

The vibration motor is an excitation source that combines the power source and the vibration source. A set of adjustable eccentric blocks are installed at each end of the rotor shaft, and the excitation force is obtained by the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block. The vibration motor has many advantages, including high utilization rate, low energy consumption, low noise and long service life. Next we will introduce how to use a DC vibration motor.

Vibration motor is installed at both ends of the rotor shaft each set of adjustable eccentric block, and then use the centrifugal force generated by high-speed rotation of shaft and eccentric block. Its purpose is to get the exciting force. It has a wide range of vibration frequencies. Only when the excitation force and power are properly matched can the mechanical noise be reduced. There are six types of vibration motors, which are classified according to starting and running mode and running speed.

Vibration motor is a power source and vibration source combined as one of the exciting source. Its exciting force is easy to use, and has the advantages of high utilization rate, low energy consumption, low noise, long life and so on. They can be applied to general vibration machinery, such as: vibration crusher, vibrating screen extension machine, vibration baler, vibration shakeout machine, vibration molding machine, vibration pile driver, vibration hoist, vibration filling machine, silo vibration arch broken anti-occlusion device and so on. They are widely used in hydropower construction, thermal power generation, construction, building materials, chemical industry, mining, coal, metallurgy, light industry and other industrial sectors.

Vibration motor is on both ends of the rotor shaft installed a set of adjustable eccentric block, the centrifugal force generated by high speed rotation shaft and eccentric block vibration force. With the improvement of vibration motor performance, the application scope has been greatly expanded. Now it is used in metallurgical industry, water conservancy industry and coal industry.

Because of the increase in demand, the number of manufacturers producing and selling vibration motors has increased a lot. We don't know how to choose when you are faced with so many types of products. In order to choose a suitable vibration motor, ATO lists some specific indicators of vibration motor selection:

For vibration motors, burning down is a common fault. So why does the vibration motor burn down? How to prevent it? This article will introduce the specific reasons and preventive measures for this, from the 6 points of anchor bolts loosening, installation, eccentric block adjustment, sealing of the protective cover, ambient temperature and heat dissipation.

The vibration motor is the core part of the vibration screening equipment. The excitation source combines the power source and the vibration source. It is a set of adjustable eccentric blocks installed at both ends of the rotor shaft. It will use the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain the exciting force. In addition, the vibration motor has a high utilization rate of excitation force, low energy consumption, low noise and long life. The excitation force of the vibration motor can be adjusted steplessly and is easy to use.

The vibration screen in the vibration motor is the key link for the smooth operation of the vibration equipment. When the excitation force is large, it is the main factor affecting the production efficiency. In order to extend the life of the vibration motor, the reasonable adjustment of the excitation force and the selection of a suitable power level cannot be underestimated. At the same time, it also plays an important role in the effective performance of the vibration motor.

Industrial Vibration motors rely on their own high-frequency vibration to generate the vibration force. Therefore, during the operation process, the motor itself will rise to a high temperature. Because of the existence of the fit clearance, the axle of the vibration motor after the temperature rise will expand. After the expansion, the axle and the bearing should have close cooperation with each other to achieve the normal operating status. Without the fit clearance, the vibration motor after the operating temperature reaches certain level will be faced with a series of problems, which might even stop operation or be burned. Hence, this problem requires more attention in vibration motor maintenance.
