    摘要: A method for controlling the operation of a motor utilizing a generic motor control module. The method includes sampling at least one motor operating criterion during operation of the motor and executing a generic control algorithm at a predetermined periodic interval. Execution of the algorithm provides a firing angle, duty cycle, or other suitable control function solution for an electronic valve for each periodic interval, thereby controlling the behavior of the motor. Additionally, the method includes firing the electronic valve at the calculated timing during each periodic interval such that the motor functions in accordance with desired motor operational parameters.

    摘要: A method and apparatus for controlling a plurality of different motors used in a corresponding plurality of power tool applications requiring different operational characteristics. In one implementation a method involves the use of a single universal control module to store a generic, non-application-specific control algorithm. The generic, non-application-specific control algorithm has at least one programmable constant. The programmable constant is selected to transform the generic, non-application-specific control algorithm into an application-specific control algorithm. The programmable constant represents a function parameter relating to a specific functionality of a specific, selected motor used in a specific, selected motor application to implement a phase control over the specific, selected motor.

    摘要: A protective redundancy circuit is provided for a power tool having an electric motor. The protective redundant subsystem is comprised of: a motor switch coupled in series with the motor; a motor control module that controls the switching operation of the motor switch; and a protective control module that monitors switching operation of the motor switch and disables the power tool when the switching operation of the motor switch fails. In the context of an AC powered tool, the switching operation of the motor switch is correlated to and synchronized to the waveform of the AC input signal. During each cycle or half cycle, the motor control module introduces a delay period before closing the motor switch and the protective control module determines the operational status of the motor switch by measuring the voltage across the motor switch during the delay period.
