Systems and methods for monitoring a wireless motor drive control system for handheld knives

A power pack for a power tool, the power pack comprising:

• an electric motor configured for driving engagement with the power tool;
• a motor controller including a relay circuit in electrical communication with the electric motor, the relay circuit comprising a switch selectively electrically connectable to a power supply, whereby electrical connection of the electric motor to the power supply powers the electric motor;
• and
• non-transitory computer-readable storage media having computer-executable instructions for monitoring operation of the power pack stored thereon, wherein when executed by at least one processor the computer-executable instructions cause the at least one processor to—
• determine an ideal state of operation of the power pack, said ideal state defining, for one or more data types represented in the input data, at least one of the following:
• an ideal range of values for the one or more data types, and a relationship between values of two or more of the one or more data types
• monitor input data relating to operation of the power pack,
• determine, based at least in part on the input data, that operation of the power pack deviated from the ideal state,
• based on the determination of deviation, cause the switch to electrically disconnect the electric motor from the power supply.
