Series JV

The modern 3-piece construction

 

The modern aluminium housing and 3-piece design ensures a low weight and high thermal conductivity for great efficiency and clearly defined, direct power transmission. 

Practice has testified to our technical concept – across the globe, even under the most diffi-cult operating conditions.

JV in detail

Unbalance motors are electro-mechanical drive units which generate circular oscillations. In contrast, linear oscillations are produced by operating two motors work-ing in opposite directions. 

Infinite oscillation amplitudes

With the motors off, the oscillation amplitude can be set for all JVM unbalance motors by adjusting the centrifu-gal weights. The oscillation frequency can also be ad-justed during operation via the optional frequency con-verter.

Operational reliability

Proven engineering from 70 years of experience and purposeful development of our technology guarantee the operational reliability that you expect. Further atten-tion to practical design details such as non-twisting cen-trifugal weights and large, legible scales make the JVM drives the market preference 

Ready for connection and easy to install

JVM unbalance motors are supplied ready for connec-tion and operation. Their space-saving geometry, easily accessible foot fastenings and transport eyes make them easy to install. JVM unbalance motors can be op-erated in every position and size 10 and up are equipped with a re-lubrication feature in the standard version.

Efficiency

The modern aluminium housing and 3-piece design ensures a low weight and high thermal conductivity for great efficiency and clearly defined, direct power transmission. Practice has testified to our technical concept – across the globe, even under the most diffi-cult operating conditions.

Dimensioning

Conservatively sized, quality components and optimised electrical performance guarantee long service lives and fast motor run-up times – this way you conserve your vibration equipment.

Quality

Every JVM unbalance motor undergoes stringent me-chanical and electrical quality controls, whereby all windings are tested. All motors are rated for S1 con-tinuous operation – even when the feed rate is set to 100%.

Special models

Whether you need divided hoods in protection system IP65, high/low temperature models, standstill heating or other special fittings – we offer many options and can offer more information upon request. 

Accessories

Details on frequency converters, D.C. injection braking devices and monitoring systems can be found in our separate information notices.
