Specialty AC & DC Drives

Spang Power Electronics specialty AC and DC drives are designed for unique OEM applications where "off the shelf" drive products just don't fit.


Spang engineers focus on incorporating state-of-the-art microprocessor-based technology into custom-designed digital drives while offering customer focus and application expertise. This experience includes specialty AC (V/Hz and vector), DC (SCR and chopper), and brushless drives for OEM applications, from fractional to 100 HP, many of which involve:


  • Shock, vibration or special ambient temperatures
  • Special voltages (including battery power sources)
  • Custom software
  • Network communications
  • Custom enclosures

The SPE100 Variable Speed Motor Mounted Drive

Spang's SPE100 is an integrated motor and control product that offers variable speed in a single package. The variable frequency AC controller mounts directly on the AC motor. The operator controls are located on top of the controller. This integrated design eliminates the need for a separately mounted inverter drive. Since Spang ships the variable speed motor package pre-configured, it does not require any special installation procedures. The SPE100 power-matched control and motor provides exceptional performance, high reliability and long service life.
