Abstract
An apparatus and method for varying a speed of a hybrid induction motor (HIM). The apparatus comprises a starting capacitor; a driving capacitor; at least one speed varying capacitor for varying a speed of a HIM by a control signal; and a controlling unit for analyzing a user's commands and outputting a control signal to vary the speed of the HIM based on a result of the analysis.
Claims16
An apparatus for varying a speed of a hybrid induction motor (HIM), comprising:
- a starting capacitor;
- a driving capacitor;
- and
- at least one speed varying capacitor for varying a speed of a HIM.
An apparatus for varying a speed of a hybrid induction motor (HIM), comprising:
- a starting capacitor for generating a starting capacitance;
- a driving capacitor for generating a driving capacitance when a HIM reaches a synchronous speed;
- at least one speed varying capacitor for varying a speed of the HIM by a control signal;
- and
- a controlling unit for outputting a control signal to vary a speed of the HIM according to a speed varying condition inputted from outside.
A method for varying a speed of a hybrid induction motor (HIM), comprising:
- starting a hybrid induction motor (HIM) by a starting capacitor;
- driving the HIM by a driving capacitor when the HIM reaches a synchronous speed;
- judging whether or not a speed varying condition has been inputted from outside;
- and
- if the speed varying condition has been inputted from outside, varying a speed of the HIM by varying a capacitance of the HIM according to the speed varying condition.
