摘要： A cordless electric mower having an energy management system that allows a user to operate the cutting blade motor of the mower at a wide range of user selected speeds. The mower is provided with a user adjustable throttle control which, when in the wide-open position allows the cutting blade motor to be rotated at a maximum, predetermined speed. When the throttle is set to some lesser speed, the system automatically implements a speed foldback routine whenever the mower encounters heavy loading which would result in an undesirably high current draw on the battery. When the speed foldback routine is implemented, the system limits the maximum amount of current that can be drawn by the motor until the excessive loading condition has been removed. Once the excessive loading condition has been removed, the speed foldback routine automatically increases the speed of the blade motor back up to almost the originally selected speed. This greatly improves the operating efficiency of the mower and thereby significantly extends the available operating time of the mower on a single charge. The state-of-charge of the battery is also monitored continuously during operation. An LED display provides the user with an indication of the approximate battery charge remaining.
摘要翻译：一种具有能量管理系统的无绳电动割草机，其允许用户以宽范围的用户选择的速度操作割草机的切割刀马达。割草机设置有用户可调节的节气门控制器，当处于大开位置时，刀片电动机可以以最大的预定速度旋转。当节气门被设定为一些较小的速度时，系统会在割草机遇到大量负载时自动实施速度折返程序，这将导致电池不期望的高电流消耗。当执行速度折返程序时，系统会限制电机可以吸收的最大电流量，直到超载条件已被移除。一旦超载条件已经消除，速度折返程序自动将刀片电机的速度提高到几乎最初选定的速度。这大大提高了割草机的操作效率，从而显着地延长了割草机在单次充电中的可用操作时间。电池的运行状态也在运行期间连续监测。 LED显示屏为用户提供剩余的大约电池电量的指示。

摘要： A dual-mode system for inexpensively operating electrically powered double-insulated devices (12), such as hand-held power tools and appliances. The system includes a cordless battery power module (14) that supplies the power and current demands of the device (12) in a cordless mode or a chopper module (21) that supplies the necessary power and current demands in a physical envelope commensurate in size and interchangeable with that of the battery power module (14). The chopper module (21) is provided with a non-filtered high efficiency converter circuit that allows the chopper module (21) to generate the power and current required by the driven device (12). The inductance of the motor (11) for the driven device (12) is used to filter the output of the chopper module (21). Eliminating the output filter from the chopper module (16) significantly reduces the cost and size of the module (16). Additionally, the need for multiple battery packs and fast rechargers is minimized by the availability of a low-cost converter. The line power module (16) includes an EMI filter (15) for filtering AC or DC input power. The chopper module (21) chops the filtered voltage, providing a series of voltage pulses having a DC voltage level that is suitable for driving the motor (11).

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.

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.
