Title:
ROTARY DRIVE SOURCE FOR ELECTRIC ACTUATOR AND ELECTRIC ACTUATOR
Document Type and Number:
Japanese Patent JP2018074833
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve downsizing of a rotary drive source of an electric actuator and further achieve downsizing of the electric actuator.SOLUTION: An rotary drive source 1 for an electric actuator includes: a hollow motor part 5 having a stator 51 and a rotor 52; a driving source output shaft 6 disposed at an inner diameter side of the motor part 5 and for outputting rotation of the rotor 52; a torque limiter 7 disposed at a downstream side of a torque transmission pass rather than the rotor 52 of the motor part 5. The torque limiter 7 is disposed in a space between an inner peripheral surface of the rotor 52 and an outer peripheral surface of the driving source output shaft 6 facing the inner peripheral surface of the rotor.SELECTED DRAWING: Figure 1
