DC Motor that works on AC
Known as a ‘Universal’ motor because
it can work on AC or DC. It has some
unique characteristics that we will
review later in the course.

Starting Devices
All of the following devices are used with
single phase motors.
1. Centrifugal Switch
2. Hot Wire Relay – no longer used
3. Current Relay
4. Solid State Relay
5. Potential Relay

Starting Devices
Three phase motors are ‘self starting’ and do
not require a ‘starting relay.’ Because of this,
they are easier to troubleshoot.

Motor/Compressor
Configurations
The HVACR industry uses compressors
which require a motor to drive the
compressor. Therefore, there are three
configurations.

1. Hermetic
The word hermetic means ‘sealed.’ So both
the motor and the compressor share the
same shaft and they are both put in a
housing and welded closed, thus ‘sealed.’
They are sometimes referred to as a ‘tin can’
or ‘welded’ compressor.

2. Semi-Hermetic
(sometimes referred to as semi-open)
The motor and the compressor share the
same shaft and the housing is accessible. In
other words, the motor can be accessed for
repair and the compressor can be accessed
for repair.

3. Open
The motor and the compressor DO NOT
share the same shaft and therefore requires
a belt or coupling to connect the motor to the
compressor.
