The newer compressors are smaller so they cost less, but are run faster to pump at the same rate. Many old hermetic compressors used a 4-pole 1500/1800RPM motor

The newer compressors are smaller so they cost less, but are run faster to pump at the same rate. Many old hermetic compressors used a 4-pole 1500/1800RPM motor, then they became a 2-pole 3000/3600RPM, and the newest VFD/inverter motors can go even faster.
