Unbalance motors are electro-mechanical drive units which generate circular oscillations. In contrast, linear oscillations are produced by operating two motors working in opposite directions.
With the motors off, the oscillation amplitude can be set for all JVM® unbalance motors by adjusting the centrifugal weights. The oscillation frequency can also be adjusted during operation via the optional frequency converter.
Proven engineering from over 95 years of experience and purposeful development of our technology guarantee the operational reliability that you expect. Further attention to practical design details like ATEX-conformity for zone 2 & 22 in standard versions – of the shelf -, PTC execution and the extraordinary strong grey-cast-housing are serving and meeting the demand and challenges of the markets and their applications.
JVM® unbalance motors are supplied ready for connection and operation. Their space-saving geometry, easily accessible foot fastenings and transport eyes make them easy to install. JVM® unbalance motors can be operated in every position and size 10 and up are equipped with a re-lubrication feature in the standard version.
The modern and state-of-the-art-design ensures great efficiency and clearly defined, direct power transmission. Field-proven success has testified to our technical concept – across the globe, even under the most difficult operating conditions.
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.
Every JVM® unbalance motor undergoes stringent mechanical and electrical quality controls, during all windings are tested. All motors are rated for S1 continuous operation – even when the feed rate is set to 100%.
