    摘要: A universal termination system is provided for power tools. The universal termination system includes criteria for each of the main switch platforms that define the number, type, location and orientation of the terminations. That is, the number, type, location and orientation of the terminations in each main switch platform are standardized and the power tools that use that type main switch platform use the main switch platform having the standardized terminations. That is, power tools that use push button switches use the push button switch with the standardized terminations, power tools that use overhang switches use the overhang switch with the standardized terminations, and power tools that use in-line VSR switches use the in-line VSR switch with the standardized terminations. In an aspect of the invention, a right-angle pin terminal is received in one or more sets of the standardized terminations. In an aspect of the invention, the switch body has features that cooperate with the right-angle pin terminals to reduce the risk of shorting adjacent terminals. In an aspect of the invention, a switch has standardized connections on a bottom of a switch body that mate with terminals of a plug-in control module. In an aspect of the invention, a switch for a hand-held power tool has cord set terminations that are screw-tab terminals.

    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 power tool has an electric motor with field windings. Each field winding includes two coils. When the motor is first energized, the two coils of each field winding are connected in series, reducing in-rush current. Upon expiration of a soft start period, the two coils of each field winding are connected in parallel. In another aspect, the field windings that are connected in series with a separate start winding when the motor is first energized. Upon expiration of the soft start period, the start winding is bypassed. In another aspect, the field windings are connected in series with a start impedance when the motor is first energized and a time delay relay having a set of delay contacts coupled across the start impedance energized. Upon expiration of the soft start period, the time delay contacts close, bypassing the start impedance. In an aspect, the motor is a universal motor.
