The sensorless speed and torque control solution, called HPSC, allows field-oriented control (FOC) for brushless motors without sensors from full stop to full speed under load. This HPSC uses a signal injection algorithm to determines the precise rotor position for a smooth startup. It offers low-noise, no vibrations and maximum power efficiency. This system contains an HPSC module 24/5. The dimension and power range can be adapted if required. The module’s firmware can be customized for every drive system.
