Drive Solutions
Smooth, reliable and quiet operation combined with compact
dimensions and product flexibility means that Control Techniques
has become the drive of choice for modern elevator systems. We
integrate with almost any lift controller and can drive virtually
any AC, DC or gearless motor. Optional software provides precision
direct-to-floor operation for increased speed and comfort.
One AC Drive to Fit Your Motor Selection
Control Techniques have years of experience designing drives for
elevators, and the result is the Unidrive SP AC Drive specially
designed and rated to give optimum elevator performance.
Unidrive SP is a thoroughbred drive for elevator applications.
The smooth Vector control gives a high quality, low noise, jerk
free ride.
Unidrive SP has a flexible integration policy that ensures it is
open to all elevator controllers.
- The drive accepts 12 different feedback devices including
Incremental, SinCos, Endat, Hiperface encoders and resolvers.
- Temperature controlled ventilation fan speed for silent
operation.
- High switching frequency (up to 16kHz) for quiet motor
operation.
