BLDC The Torque Parameter Estimation Apparatus and Method of BLDC Motor for Torque Calibration of The Dental Implant-Motor

摘要

A BLDC motor for torque correction of a dental implant motor capable of performing torque correction of a dental implant motor through torque parameter estimation of an electric motor without using a fixed part for performing torque correction of a motorized implant treatment device An apparatus and method for estimating torque parameters, the method comprising: (a) driving a three-phase Y-wire BLDC motor to a maximum; (b) measuring the rotational speed and current of the BLDC motor; (c) estimating a counter electromotive force constant based on the measured rotational speed and current; And (d) estimating a torque constant for torque correction of the implant motor using the estimated back electromotive force constant, thereby implementing a torque parameter estimation method of a BLDC motor for torque correction of the dental implant motor.;
