Energy-saving Synchronous Motor and
Inverter Systems
FESPAC Series
Combining a general-use synchronous motor with
integrated permanent magnet (IPM motor) and
dedicated inverter, the FESPAC Series is a compact,
lightweight, efficient variable-speed drive system
to replace the widely used combination of induction
motor and inverter drive. |
|
- High-efficiency, energy-saving operation (35%
reduction in overall power loss)
- Compact, lightweight, space-saving design
(reducing the motor frame by 1-2 sizes has
reduced volume by an average of 35%, and weight
by an average of 40%, compared with induction
motors)
- High-performance, multifunctional operation by
the dedicated inverter (PID control, RS-485
communications built-in)
- Careful consideration given to peripheral
equipment (built-in inrush current suppression
circuit, accommodates an external 24V power
supply)
- Wide range of maintenance and protective
functions (cumulative operating hours display,
main circuit capacitor life display)
- Easy operation and wiring (touch panel remote
operation, easily removable terminal board
cover)

Two types available:
Low-torque type
(without polar sensor, for fan or
pump use)
and
constant-torque type
(with polar sensor, for general
equipment use).
