TM-21 & TM-16 Compressor and
Clutch Maintenance
Operation
A stationary field coil is mounted on the compressor body eccentric with the
shaft. A pulley assembly, consisting of a pulley, disc and hub is mounted on the
shaft of the compressor. The hub and disc are flexibly connected with flat springs
that when extended hold the disc slightly away from the pulley web (friction
Surface).
When an electric current flows through the field coil, a magnetic field is created.
The magnetic field pulls the disc against the pulley web and compresses the flat
springs. This causes the hub and disk to rotate with the pulley.

2.
Pulley Assembly:
