Benefits of
Written-Pole® Single-Phase Motors
Page 2
The
following summary provides an overview of benefits of Written-Pole®
single-phase motors. Based on
Written-Pole® technology, a patented concept developed by Precise
Power Corporation, these innovative single-phase motors offer many
advantages over conventional single or three-phase electric motors.
2) Energy Efficient
Operation
The synchronous mode of operation under
which
Written-Pole®
single-phase motors operate allows for very high operating
efficiencies, comparable to those of premium efficiency three-phase motors
with similar ratings. The resulting reductions in transformer loading and
operating costs can represent a significant advantage over comparable
installations using three-[phase motors and phase converters.
The high operating efficiency of a V
single-phase motor is made possible by the fact that its synchronous mode
of operation eliminated losses commonly associated with the slip in
conventional induction motors. By eliminating the resulting rotor losses,
Written-Pole®
single-phase motors are able to substantially reduced total
losses, improving operating efficiency.
3) Unity Power Factor
Operation
The Synchronous mode of operation also
results in near unity power factor operation at rated load (slightly
leading at part load) further reducing transformer and distribution line
loading. The following table illustrated the comparable operating
efficiency and power factor of a
Written-Pole®
single-phase motor with conventional single and three-phase
induction motors.
