February 3, 2021

Motovario offers a range of motovariators and motovariator combinations including:

S / TFX Series

The S and TFX Series are valid alternatives to electronic drives. They are easy to use and to maintain. They offer high efficiency, bidirectional rotation and silent, vibration-free running. The S-type in cast iron includes a wide range of models with flange, feet, or in compact version and is available in seven sizes from 003 to 100, with input shaft or in motorized version. The SD version with differential can also be used in applications with speeds close to 0. The low-cost, light weight TXF versions in aluminium are available in sizes 002, 005 and 010.

• S-Series available sizes include 003-005-010-020-030-050-100 with power up to 9.2 kW and torque value max of 144 Nm
• TXF-Series available sizes include 002-005-010 with power up to 2.2 kW and troque value max of 12 Nm
• Shafts: case hardened and tempered 20MnCr5 steel (UNI8550)
• Internal components: 100Cr6 heat-treated steel
• Control handwheel positionable on either side
• Slipping speed to max load at 5%
• Regulation sensibility: 0.5 rpm
• Painted with RAL 5010 blue epoxy-polyester powder

VH / VHA Series

The VH/VHA series includes a motovariator in combination with a helical gear reducer. The VH-Series in cast iron is available with variators from size 003 to 100 combined with helical gearmotors in cast iron from size 030 to 125. The VHA version in aluminum is available with variators from size 002 to 010 combined with helical gearmotors in aluminum from size A30 to A60.

• Compact version
• Painted with RAL 5010 blue epoxy-polyester powder
• VH Series available sizes include 003-005-010-020-030-050-100 combined with helical gear reducer 030-040-050-060-080-100-125
• VH power up to 9.2 kW and torque value max 5,000 Nm
• VH cases in G200 grey cast iron for high strength and optimized with FEM analysis
• VHA Series available sizes include 002-005-010 combined with helical gear reducer A30-A40-A50-A60
• VHA power up to 2,2 kW and torque value max 480 Nm
• VHA cases in die-cast aluminium alloy

S+NMRV / TXF+NMRV Series

The S+NMRV / TXF+NMRV series includes a motovariator in combination with a worm gear reducer. The S+NMRV is available with variators in cast iron from size 003 to 100 combined with NMRV worm gear reducers from size 030 to 150. The TXF+NMRV is available in aluminium in sizes 002, 005 and 010 combined with NMRV worm gear reducers from size 030 to 130. The VHA version in aluminum is available with variators from size 002 to 010 combined with helical gearmotors in aluminum from size A30 to A60.

• Painted with RAL 5010 blue epoxy-polyester powder
• S+NMRV series available sizes include S-variator combined with worm gear reducer in sizes 030-040-050-063-075-090-105-110-130-150

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
