Synchronous Motor Family
HURST® permanent magnet synchronous motors are reversible
permanent-split capacitor motors identical in construction to the
HURST® stepping motors. The 60 Hz can-stack motors operate at
synchronous speeds of 300 and 600 RPM. High quality gearing is
available for the can-stack motors. The ceramic rotor magnet
material provides a relatively high flux resulting in a good torque
to size ratio at moderate cost. In addition the permanent magnet
construction provides inherent dynamic braking and low rotor speed
for quiet operation and rapid acceleration. The disadvantages of
permanent magnet motors are a limited ability to accelerate inertial
loads and a high sensitivity to the parameters of voltage and
phasing capacitor. The first of these problems may be minimized by
gearing or in some cases flexible couplings. The sensitivity to
voltage and phasing capacitor directly affects the directional
reliability of both starting and running under load. In HURST® motor
designs directional reliability is a primary consideration and is
assured when motors are operated with the recommended capacitor
within a voltage range of 10% of nominal.
