Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
A kind of motor protection device, referring to Fig. 1-3, including motor 101, flywheel 102 and protective cover 103, in the present embodiment
Motor be double output shaft electric machines, motor 101 includes main output shaft, the auxiliary output shaft 1011 and casing 1012 of the other end of one end,
Flywheel 102 is arranged on auxiliary output shaft 1011, and protective cover 103 covers flywheel 102 and is fixed on casing by some connectors 104
On 1012, contact-making switch 105 is provided with each connector 104, contact-making switch 105 controls open/close, machine by protective cover 103
Controller 106 is provided with shell 1012, contact-making switch 105 is electrically connected with controller 106, controller 106 and motor 101 and electricity
