Three-phase asynchronous vibrator motor

Introduction to three-phase asynchronous vibration motor

The three-phase asynchronous vibration motor is a vibration source that combines a power source and a vibration source, and is usually used for small and medium-power drive devices. Its working principle is based on the interaction between electromagnetic induction and electrodynamics. When three AC power coils input sinusoidal current, a rotating magnetic field is formed in the stator, and the rotor is driven to rotate through the electromagnetic force generated in the secondary winding. Due to the salient poles on the rotor, the three-phase asynchronous vibration motor can generate a large starting torque when starting, which is particularly suitable for starting and driving equipment with heavy loads and large inertia.

Working principle of three-phase asynchronous vibrator motor

The three-phase asynchronous vibration motor consists of a fixed part (stator) and a rotating part (rotor). Three mutually balanced AC power coils are wound on the stator, and a rotating magnetic field is generated in it through three sinusoidal currents with a difference of 120 degrees; two sets of windings are wound on the rotor - the main winding and the secondary winding. When the rotating magnetic field in the stator acts on the winding on the rotor, current will be generated in the secondary winding, generating electromagnetic force, thereby driving the rotor to rotate.

Features of three-phase asynchronous vibrator motor

Good starting performance: Due to the salient poles on the rotor, the three-phase asynchronous vibration motor can generate a large torque when starting.

Lower no-load current: When the load changes, the no-load current changes in a small range.

Wide speed regulation range: Speed ​​regulation can be achieved by changing the position of the salient poles on the rotor.

Simple structure: Compared with other motors with auxiliary equipment such as brakes or inverters, the structure of the three-phase asynchronous vibration motor is simpler.

Three-phase asynchronous vibration motors are widely used in various vibration machines, such as vibration screening machines, vibration mills, vibration balers, vibration sand-falling machines, vibration molding machines, vibration pile drivers, vibration hoists, vibration filling machines, and vibration arch breaking of silos. In addition, they are widely used in hydropower construction, thermal power generation, construction, building materials, chemicals, mining, coal, metallurgy, light industry and other industrial sectors.

Three-phase asynchronous vibration motors are key components in various industrial vibration equipment, providing controlled vibration for material handling and processing applications.
