Vibration motors / vibrators AV & VV

Vibration motors are technical devices that generate and transmit mechanical vibrations by supplying energy. These vibration motors are mostly used in bulk material handling processes, for conveying, screening, loosening or material compaction and at neuralgic points in mechanical systems and many more.

Vibration motors (also called vibrators, vibration motors, unbalance motors, vibration motors, unbalance drives, vibrators or external vibrators) are specially manufactured for vibration technology machines in which bulk materials are conveyed, separated, compacted, distributed, loosened or sorted by vibration. Vibration motors can be varied depending on the application.

Common vibrator designs:

  • Electric vibration motors with adjustable rotating unbalance weights
  • Richter exciters or unbalance exciters with adjustable rotating unbalance weights
  • Pneumatic vibrators with rotating unbalance weights
  • Pneumatic vibrators with linear vibrating masses
  • Pneumatic vibrators with vibrating and beating masses
  • Beaters with beating mass
  • Electromagnetic vibrators with vibrating mass
  • Hydraulic vibrators with rotating unbalance

Common vibration or pulse types:

  • Vibration motors and vibrators as well as directional exciters with radial sinusoidal vibration
  • Vibrators with linear sinusoidal vibration
  • Vibrators with linear vibration combined with impact pulses
  • Beaters with impact pulses

Applications of vibration motors (selection)

  • Foundry industry
  • Road and civil engineering
  • Building materials industry
  • Packaging technology
  • Food technology
  • Chemical industry
  • Pharmaceutical industry
  • Automotive
  • Waste Management & Recycling
  • Mining & Surface Mining

Features of vibration motors

  • Heat resistant
  • Resilient
  • Moisture resistant
  • Robust
  • Low maintenance
  • Durable
  • Continuous operation possible
  • Low energy consumption
  • Quiet

The vibration motors and vibrators are usually equipped with a foot or flange connection and can thus be coupled to common end applications of vibration machines and systems.

The vibration and impact pulses in vibration motors and vibrators are created by built-in unbalanced weights or masses, which generate alternating centrifugal forces through rotation or linear motion. These forces are absorbed by coupled components such as conveyors, silos or screening machines etc. and vibrate or shake them.

When using the vibration motors, some safety instructions must be observed

All versions of vibration motors must not be used without the use of centrifugal weights and protective covers. It is especially important to secure the electrical connection, which must also be regularly checked for defects. If there are any irregularities in the connection cables, these must be rectified immediately to ensure the function of the vibration motors and the safety of your employees. Likewise, special explosion-proof vibration motors must be used in hazardous areas. Regular maintenance of the devices is essential.

FAQ Vibration motors

Before mounting vibration motors, the supporting surface or screw-on surface should be thoroughly cleaned. The removal of grease, oil, rust and paint forms the basis for successful assembly. Furthermore, the vibration motors to be mounted should be checked for their perfect condition so that they can then be mounted using suitable tools.

The vibration motors may only be connected by an authorized electrician, as the connections must comply with the regulations of the power supply company. Equally important here is the thorough sealing of cable glands, terminal box covers and dummy plugs. Be sure to leave this work to a professional.

If a vibration motor fails, it can of course be replaced. However, it is essential to ensure that both vibration motors are identical and have the same centrifugal force setting.

Of course, there are spare parts for vibration motors. For that, you don't need to do anything but contact us:
