Feature

• Our proprietary sensorless technology (current waveform normative type) is used to control the motor by focusing on the waveform characteristics of the current.
• Compared to the general voltage sensor-less drive system, the sensor-less technology does not control the motor by voltage, thus enabling more stable operation against voltage fluctuations.
• Speed control is performed by PWM (pulse width modulation) control using the sensorless drive function and a general-purpose microcomputer (16 bits).
