Title:
MOTOR OR LINEAR MOTOR OUTPUT CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2022166775
Kind Code:
A
Abstract:
To provide a motor or a linear motor output control system that improves the efficiency of the mechanical output of the motor or linear motor by configuring the mechanical output of the motor or linear motor to be small in the low speed range and large in the high speed range.SOLUTION: The connection of a switching element that can independently control rotating pole pairs 15, 15 of a rotor 11 constituting a motor and fixed pole pairs 17, 17 of a stator 12 is performed, and the switching elements are numbered. Same as the plurality of rotating pole pairs, the plurality of fixed pole pairs are controlled so as to be divided into a first fixed pole group or a first rotating pole group indicated by a solid line and a second fixed pole group or a second rotating pole group indicated by a dotted line. The efficiency of the mechanical output can be improved by dividing the control into a full operation pattern in which both the first group and the second group are operated and an intermittent operation pattern in which only the first group is operated.SELECTED DRAWING: Figure 2
