Title:
MOTOR DRIVE
Document Type and Number:
Japanese Patent JP2001119988
Kind Code:
A
Abstract:

To provide a highly practical motor drive, requiring no measurement of a resonance point for individual motor having different mechanical resonance point or torque response.

In this motor drive, an output current from a speed control section, an output current from a motor current detecting section, and a micro output current from a resonance point setting section for setting arbitrary frequency and amplitude are inputted to an operating section and a mechanical resonance point of the motor is measured, based on an output current from the operating section having the micro output current.
