CUSTOM BUILT INDUCTIVE REACTORS FOR AC MOTOR CONTROLLERS

AND CUSTOM BUILT RANGE OF DC CHOKES AND AC REACTORS

Custom built range of inductive reactors for AC motor

controllers

Designed to customer specification

Using either our standard format

or to customers’ own drawings or requirements

3ph line reactor

A comprehensive range of custom built inductive reactors used in conjunction with AC motor controllers.

They are connected in differential mode configuration and are used in the following three applications:

The reactor is installed between the input mains filter and the motor controller and in this application the low frequency

electromagnetic interference is improved by levelling the input current drawn. This will cause a typical volt drop of between 2-4% of

the nominal mains voltage.

The reactor is installed between the inverter and the motor and enables the correct decoupling of the two devices. Where the reactor

is used in a system with a single power supply for multi-axis or mandrel control devices. The reactor is installed between the mains

filter and the power supply to de-couple it from the mains supply.

Using either our standard format

or to customers’ own drawings or requirements

A comprehensive range of custom built DC chokes and AC reactors in both

single and three phase options.

These chokes and reactors are custom built or can be designed to customer

drawings or requirements. Where dimensions are not critical these units are

designed around our standard frame sizes.

Alternatively units can be produced to customer drawings or customers own

requirements.
