A power equipment system with a plurality of power equipment units each including a working tool. Each of the power equipment units may include provisions permitting independent connection with both a battery and an electric motor, wherein the battery and electric motor may be moved between different power equipment units as needed. In some embodiments, a first power equipment unit may provide an identity information signal of the associated working tool to a controller of either or both of the motor and the battery. The identity information may limit or control one or more operating parameters of the motor when the motor is installed on the first power equipment unit.

1. A power equipment system, comprising: an electric motor comprising a motor housing, an output member, and a motor controller;a battery comprising a battery housing and a battery controller, the battery housing separate from the motor housing, the battery adapted to provide power to the motor;a first power equipment unit and a second power equipment unit each independently operable to simultaneously receive both the motor and the battery, the first and second power equipment units each comprising: a battery interconnect adapted to electrically couple with the battery;a working tool;a coupler adapted to mechanically interconnect the output member of the motor with a driven member associated with the working tool; anda motor interconnect adapted to electrically couple with the motor;wherein the first power equipment unit further comprises a first tool controller adapted to provide an electrical identity information signal regarding the first power equipment unit to one or both of the motor controller and the battery controller when the motor and the battery are selectively coupled to the first power equipment unit. 2. The system of claim 1, wherein the identity information signal specifies an output speed to be provided by the electric motor. 3. The system of claim 1, wherein the identity information signal specifies an output power to be provided by the electric motor. 4. The system of claim 1, wherein the second power equipment unit further comprises a second tool controller adapted to provide a second identity information signal regarding the second power equipment unit to one or both of the motor controller and the battery controller when the motor and the battery are selectively coupled to the second power equipment unit, wherein the second identity information signal is different than the identity information signal provided by the first tool controller. 5. The system according of claim 1, wherein at least one of the first and second power equipment units, the battery, and the motor is adapted to: detect when the motor reaches an overload threshold; and reduce an output speed or power of the motor upon reaching the overload threshold. 6. A power equipment system, comprising: a motor comprising a motor housing and a motor controller;a battery comprising a battery housing and a battery controller;first and second power equipment units each independently adapted to simultaneously receive the motor and the battery, wherein each of the first and second power equipment units comprises: a body defining a motor receptacle sized to receive the motor housing, and a separate battery receptacle sized to receive the battery housing;a battery interconnect in or near the battery receptacle to electrically couple with a connector on the battery housing;a working tool;a motor coupler in or near the motor receptacle to mechanically couple an output member of the motor with a driven member coupled to the working tool;a motor interconnect in or near the motor receptacle to electrically couple with a connector on the motor housing; anda tool controller to generate an electrical identity information signal to one or both of the motor controller and the battery controller,wherein the tool controller of the first power equipment unit generates the identity information signal regarding the first power equipment unit when the motor housing and the battery housing are received within the motor receptacle and the battery receptacle, respectively, of the first power equipment unit, andwherein the tool controller of the second power equipment unit generates the identity information signal regarding the second power equipment unit when the motor housing and the battery housing are received within the motor receptacle and the battery receptacle, respectively, of the second power equipment unit. 7. A method of operating a plurality of power equipment units, the method comprising: attaching a battery comprising a battery housing at a first location on a first power equipment unit selected from at least two different power equipment units;attaching an electric motor comprising a motor housing and a motor controller at a second location on the first power equipment unit;transmitting, from a tool controller of the first power equipment unit, an identity information signal corresponding to the first power equipment unit;receiving, with the motor controller, the identity information signal; andoperating a first working tool associated with the first power equipment unit, the first working tool operating under power provided by the electric motor and battery. 8. The method of claim 7, further comprising attaching a second battery comprising a second battery housing to the first power equipment unit while the battery is attached to the first power equipment unit. 9. The method of claim 7, comprising: removing the battery and the motor from the first power equipment unit; andattaching the battery and the motor to a second power equipment unit. 10. The method of claim 7, further comprising: automatically selecting, with the motor controller, a first output parameter of the motor based upon the identity information signal received by the motor controller. 11. The method of claim 7, further comprising: detecting when the motor exceeds an overload threshold; andreducing a speed or power of the motor automatically in response to exceeding the overload threshold. 12. The method of claim 11, wherein the overload threshold is specified within the identity information signal.
