Independent brake unit

The new concept is to apply an independent brake unit to a standard flanged explosion proof motor or to a transmission unit. The flanges input and output follow both IEC or NEMA standards. Beside the face to face lines (IEC and NEMA), it is also available the COMPACT LINE version, suitable to be applied to the NDE of an electric motor or to any transmission unit. The VIS brakes are certified as independent components. It means that there are not coupling procedures in order to define the certification.

The VIS brake is available in IEC flange face to face version (B5 63 to 315 ), NEMA standards (56 to 405) and COMPACT LINE for the mounting in the rear part of an electric motor or to a transmission unit. By choosing the VIS brake, it’s very easy to make an explosion proof brake motor, reducing costs and delivery time.

High performance, heavy duty instant break systems

The performance of VIS brakes is particularly high and the strong structure makes them suitable for very heavy duty and for every kind of application (hoisting, travelling, positioning…) and the VIS brakes don’t need periodical maintenance such as adjustment of gap on work site. The braking torque values are included between 3 to 16.000 Nm* and the electromagnets fitted inside the VIS brakes can be AC three phase or DC with built in rectifier*.

The cost of a standard explosion proof motor plus the VIS brake is considerably lower than an explosion proof brake motor and the lead time and reliability are much better.
