Warner Electric Compressor Clutch

Service & Installation Instructions

An Altra Industrial Motion Company

Failure to follow these
instructions may result in product
damage, equipment damage, and
serious or fatal injury to personnel.

General

This compressor clutch has been developed
specifically for automobile air conditioning
applications. Properly installed, it will provide
maintenance free service. The clutch, using a
stationary field principle, does not require slip
rings or brushes.

The clutch consists of two major components,
a stationary magnetic field assembly and a rotor­pulley assembly. The field assembly is mounted
on bosses on the compressor. The rotor­pulley assembly is mounted to the compressor
crankshaft and driven by V-belts from the engine
crankshaft pulley. Electricity energizes the
clutch field to couple the clutch magnetically,
thus driving the compressor. Deenergization of
the field releases the clutch and uncouples the
compressor.

Wiring

The coil in the field assembly has a single
leadwire (hot) and is grounded to the field shell.
It will only be necessary to connect this leadwire
into the electrical system as recommended by
the manufacturer of the air conditioning unit.
Figure 1 is an example of a typical system.
