Power tool including conduction angle control

A method for controlling a conduction angle of a power tool motor, the method comprising:

• receiving, by a motor controller, a desired speed signal;
• monitoring, by the motor controller, a speed of the motor;
• generating, by the motor controller, an error value signal between the desired speed signal and a monitored speed;
• generating, by the motor controller, a conduction angle signal based on the error value signals, wherein the conduction angle signal is a splined conduction angle signal;
• determining, by the motor controller, whether the conduction angle signal is greater than the error value signal;
• increasing, by the motor controller, the conduction angle output by a power switching network in response to the conduction angle signal being determined to be greater than the error value signal;
• decreasing, by the motor controller, the conduction angle output by the power switching network in response to the conduction angle signal being determined to be less than the error value signal;
• determining, by the motor controller, whether the conduction angle is less than a maximum threshold value;
• and
• maintaining, by the motor controller, the conduction angle in response to determining that the conduction angle is not less than the maximum threshold value.
