Abstract
A plural motor assembly includes a first motor generating a parameter, a control circuit electrically connected to the first motor for detecting the parameter and outputting a switch signal while the parameter is abnormal, and a second motor electrically connected to the control circuit and operating in response to the switch signal. Thus, when one motor is damaged, the speed of rotation of the other motor is increased to maintain normal operation.
Claims9
A structure of a plural motor assembly, comprising:
- a first motor generating a parameter;
- a control circuit electrically connected to said first motor for detecting said parameter, and outputting a switch signal while said parameter is abnormal;
- and
- a second motor electrically connected to said control circuit and operating in response to said switch signal,
- wherein said first motor and said second motor are initially operating at the same speed, and while said parameter is abnormal said second motor increases said speed in response to said switch signal.

A method for controlling a plural motor assembly, comprising steps of:
- using a control circuit to drive a first motor generating a parameter;
- detecting said parameter, and outputting a switch signal while said parameter is abnormal;
- and
- operating a second motor in response to said switch signal,
- wherein said first motor and said second motor are initially operating at the same speed, and while said parameter is abnormal said second motor increases said speed in response to said switch signal.
