Output filter for motor drives

Tuesday, 08 July, 2008 | Supplied by: Westek Electronics Pty Ltd


The Schaffner Model 510 output filters reduce voltage slew rate (dV/dt) from inverter drives for variable-speed motors. High-voltage slew rates can cause overstressing of long motor drive cables and cause insulation breakdowns in motor windings.

The Schaffner output filters are suitable for servo drives, closed loop vector drives and robotic applications and generally for both long and short drive cable set-ups. The Schaffner Model 510 output filters have very low output impedance and are therefore ideally suited to the dynamic changes typical of servo operations.

There are eight models in the series ranging in ratings from 1.5 to 30 kW (4 to 66 A). The Schaffner Model 510 output filters are characterised by very low losses and are also protected against overload by a fan and internal temperature monitoring.
