LEESON FHP Series NEMA 4x Variable Speed Drive - Manual (Page 6)

v
In addition to standard 3-phase induction motors, the
following motor types may be used with the FHP Series:
• Permanent split capacitor (PSC)
• Shaded pole
• AC synchronous
Warning
Caution should be taken when operating fan-cooled
motors at low speeds because their fans may not
move sufficient air to properly cool the motor. LEESON
recommends “inverter-duty” motors when the speed
range is beyond 10:1.
ƽ
The following motor types MAY NOT be used:
• Split phase
• Capacitor start
• Repulsion induction
• Series Universal AC/DC
• Any motor with starting switch (centrifugal or relay)
and/or separate starting winding.
