Switchless
Motors
The revolutionary switchless motors used
in Artesian Spas® drive high-water volume
pumps that are long-lasting and virtually
trouble-free. The switchless motor design
does not require a mechanical switch to
take it from the start position to run
position, which greatly increases the efficiency
of the motor. It also diminishes operating
noise, such as the vibration and electrical
noise heard with conventional motors. An
added bonus of the switchless motor is
this design requires from 10 to 16 fewer
parts than a conventional motor, which
means many potentially problematic components
have been eliminated. The life of our switchless
motor can be measured in tens of years
instead of hundreds of hours.
Technical
Information
What are the main design differences
between a switched and switchless design?
Overall, the focus of the switched v. switchless
design debate is around two-speed designs.
Switched designs include split phase, cap
start, cap start/cap run. The permanent
split capacitor or PSC design is switchless.
There
are three motor designs that can be considered: Pole
Changer – motor contains
high and low main and high start only;
motor only starts using high speed start after which the switch removes the
start and energizes high or low main. PSC/Split Phase – motor
contains high and low main as well as high and low start; motor with energize
only the main/start combination that is
desired; low speed starting torque is comparable with high speed. PSC/PSC – motor
contains high and low main as well as high and low start; motor will energize
only the main/start windings that are desired; low
speed starting torque is significantly less that high speed.
