This solution aims to help customers implement the low-speed sensorless control function for IPM motor, which is difficult to develop, into their various equipment easily.
Suitable for applications that require torque and high efficiency at zero/low speeds.
In addition to the conventional high-voltage version (AC200V), a low-voltage version (DC24V) has been newly released. Please use according to the voltage of your motor.
By adopting position estimation with pulse voltage*1, it can output the rated torque at zero to low speeds (around hundreds of rpm), which conventional sensorless vector control*2 could not support.
*1: At zero/low speeds. At high speeds, drives by switching to position detection with BEMF observer.
*2: Renesas sample software “Sensorless Vector Control for Permanent Magnet Synchronous Motor (R01AN6307)”
Having the initial magnetic pole position estimation function, this solution enables quick position estimation within 0.2 seconds regardless of the motor position.
In addition, achieves magnetic pole position estimation errors under ±10deg (equivalent to GP INV).
⇒Enables quick startup and smooth motor control.
Since motor positions can be estimated even at the low-speed range, this solution enables motor drive with minimum necessary current according to the load at low-speed range, which the conventional sensorless vector control*1 didn’t support.
⇒Can improve energy efficiency and reduce current consumption, suitable for battery applications.
