Title:
SERVO-DRIVING METHOD OF MOTOR
Document Type and Number:
Japanese Patent JP2006054978
Kind Code:
A
Abstract:
To start a motor regardless of a temperature of a motor bearing, by detecting the temperature and using optimal variable gain and variable time constant.
A servo-driving method of the motor is a method to start the motor M irrespective of the temperature by inputting the variable gain K and the variable time constant Ts into a servo-system 50 as parameters, wherein the variable gain and the variable time constant are obtained by incorporating a friction coefficient (12) and a viscosity coefficient (10) in accordance with the bearing temperature 31.
