Classification: CPC H  B | IPC B  H

Claim 8:
9. A method of braking a motor in a power tool, the method comprising:
controlling, with a motor controller of the power tool, power delivered to the motor based on a position of a trigger,
determining, with the motor controller, to brake the motor during operation of the motor,
activating, in response to determining to brake the motor and with the motor controller, a brake switch to connect a stamped brake resistor to the motor, the stamped brake resistor including a terminal portion and a resistive portion, wherein the resistive portion includes a planar serpentine path forming a plurality of leaves and a gap between each leaf, the resistive portion further including a first leg, a second leg perpendicular to the first leg, a third leg, and a fourth leg perpendicular to the third leg, and wherein the planar serpentine path includes a filling substance located within each gap formed between adjacent leaves, the filling substance configured to maintain a shape of the stamped brake resistor, and
receiving, in response to the brake switch being activated and with the stamped brake resistor, motor current from the motor to thereby brake the motor.
