Vibration reduction system and method for power tools

A power tool comprising:

• a housing;
• a motor within the housing, wherein the motor includes a rotor and a stator and the rotor is configured to produce an output;
• a magnetically susceptible fluid located within the housing;
• an inductor within the housing and configured to introduce a magnetic field to the magnetically susceptible fluid to provide vibration control;
• a sensor configured to indicate an amount of vibration experienced by the power tool;
• a wireless communication controller configured to communicate with an external device;
• and
• an electronic controller including a memory and an electronic processor, the electronic controller coupled to the sensor, to the wireless communication controller, and to the inductor, the electronic controller configured to:
• receive, from the external device via the wireless communication controller of the power tool, a user-selected sensitivity level for the vibration control, wherein the sensitivity level is set by a user via a graphical user interface of the external device, and wherein the sensitivity level controls (i) a vibration threshold that indicates a vibration level to be experienced by the power tool before the inductor is controlled to provide the vibration control to dampen vibration and (ii) an aggressiveness of the vibration control,
• control the motor to produce the output,
• generate, with the sensor, an input signal indicating the amount of vibration experienced by the power tool,
• receive the input signal from the sensor indicating the amount of vibration experienced by the power tool,
• determine a value for the amount of vibration experienced by the power tool based on the input signal,
• determine whether the value for the amount of vibration experienced by the power tool is less than the vibration threshold,
• generate, in response to the value for the amount of vibration experienced by the power tool being equal to or greater than the vibration threshold, a control signal for the inductor based on the input signal and the sensitivity level to control the magnetic field to provide the vibration control,
• transmit the control signal from the electronic controller to the inductor, and
• provide the control signal to the inductor to control the magnetic field to introduce the magnetic field to the magnetically susceptible fluid located within the housing of the power tool.
