V-TORQ

Non-Contact Variable Speed Drive for Variable Speed Control

The V-TORQ Non-Contact Variable Speed Drive is designed for applications where the speed of the driven side needs to be adjusted manually or automatically during operation. V-TORQ combines the benefits of non-contact power transmission with simple speed control, making it ideal for controlling flow or pressure in pumps and fans, with energy savings of up to 50%.

Key Features

V-TORQ is a combination of an A-TORQ and a Motor Sliding Base (MSB)
Suitable for motor power from 7.5 kW to 375 kW
Speeds up to 3,600 rpm
Compatible with motors built before 1999
ATEX-compliant
No physical contact between motor and driven equipment
Suitable for pumps, fans, and compressors

What problems does V-TORQ solve?

Energy Savings

By vary the speed of the pump or fan with a V-TORQ, significant energy savings can be achieved:

Immediate energy savings of up to 50%
Energy-wasting throttling valves can be fully opened

Result: Lower energy costs and reduced CO₂ emissions.

Less Maintenance

V-TORQ prevents mechanical wear thanks to its non-contact design:

Speed control without shaft current through bearings
No need for laser alignment
Less malfunctions and mechanical failures

Result: A simple, low-maintenance variable drive system that keeps your installation reliable and efficient.

Less Repairs

Thanks to the adjustable coupling and damping characteristics, V-TORQ protects components from overload:

Strong shock load damping (acts as a mechanical soft starter)
Motor load is optimally matched to process requirements
No harmonic distortion or EMC interference
Extended service life of bearings, seals, and motors

Result: Lower repair costs, longer lifespan of key components, and improved system reliability.

Less Downtime

V-TORQ reduces the risk of unplanned downtime and simplifies maintenance tasks:

Back pull-out pumps are easier to service with up to 200 mm of retraction via the MSB
No spacer required
No complex realignment necessary
Speed can be adjusted without interrupting production
Ideal for seasonal settings (e.g. summer/winter) or integration into process automation

Result: Increased uptime, faster maintenance, and greater availability
