摘要： A motor control module designed to control operation of a plurality of different motors in a plurality of different tools a power tool uses an electronic clutch in the module in conjunction with a mechanical clutch in the tool to protect the tool against an overload event. The module is adapted to implement methods to provide aural and/or tactile feedback to a tool user as a warning of an impending or current fault condition in the tool. The module can prevent power from inadvertently turning on either after an overload event has cleared with the tool plugged in and its power switch on, or after plugging in the tool within the power switch on. The control module is adapted to provide torque control for the power tool, to estimate tool motor temperature and to inform a tool user when a servicing need in the tool is required.

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.

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 thermal control circuit (49) for inexpensively protecting the power interface of cordless and dual-mode powered devices (12), such as hand-held power tools and appliances. The powered device includes a motor (11) that is operable in a preselected voltage range. A switch assembly (110) controls the flow of electrical energy to the motor (11). A power module (14, 16) is configured to supply electric power and to mate with the low-voltage DC power tool (12). The power module (14, 16) is adapted to provide a DC voltage in the preselected voltage range suitable for powering the low-voltage DC power tool (12). A case (91) for the power tool (12) has a pre-defined envelope for electrically and mechanically mating with the power module (14, 16). A power interface that includes at least two terminals, electrically couples the power module (14, 16) to the motor (11). The thermal control circuit (49) protects the power interface from damage caused by an overtemperature level. The thermal control circuit (49), in response to detecting an operating temperature that exceeds the overtemperature level, permanently interrupts the flow of electricity from the power module (14, 16) to the motor (11).

摘要： The motor speed control circuit senses average back EMF as a measure of motor speed. The back EMF charges a capacitor circuit which accumulates charge and develops a voltage indicative of the motor speed. A sample and hold circuit may be used to sample the back EMF when the motor is switched off during each cycle. This voltage is compared with a reference voltage indicative of the desired motor speed. An error signal is generated by comparing the desired speed with the actual speed and this error signal is used to generate a variable duty cycle pulse train which gates the power controlling transistor on and off to control motor speed. A logic gated or SCR gated voltage boosting circuit operates in synchronism with the gating pulse train to drive the power transistor hard into saturation. This lowers the resistance of the power transistor, causing less energy dissipation as waste heat. The motor speed control circuit produces a family of torque-speed curves which maintain speed constant until a break point is reached, whereupon speed falls inversely proportional to torque. A torque control circuit monitors the motor current and maintains that current at a user selected level to thereby select a desired output torque.
