Abstract
A power trowel that includes a handle, a housing, a blade assembly including a trowel blade, a motor coupled to the blade assembly, a plurality of sensors configured to generate output signals related to an operational state of the power trowel, and a controller connected to the motor and the plurality of sensors. The controller is configured to receive the output signals from the plurality of sensors, determine, based on the output signals, a speed setting for the blade assembly and a pitch angle for the trowel blade, and control the motor to drive the blade assembly at the speed setting with the trowel blade at the pitch angle.
Claims16
A power trowel comprising:
- a handle;
- a housing;
- a blade assembly including a trowel blade;
- a motor coupled to the blade assembly;
- a plurality of sensors configured to generate output signals related to an operational state of the power trowel;
- a controller connected to the motor and the plurality of sensors, the controller configured to:
- receive the output signals from the plurality of sensors,
- determine, based on the output signals, a speed setting for the blade assembly and a pitch angle for the trowel blade, and
- control the motor to drive the blade assembly at the speed setting with the trowel blade at the pitch angle.
A method of controlling a power trowel, the method comprising:
- receiving, from a plurality of sensors, output signals related to an operational state of the power trowel;
- determining, using an electronic controller, a speed setting for a blade assembly and a pitch angle for a trowel blade based on the output signals related to the operational state of the power trowel;
- and
- controlling a motor to drive the blade assembly at the speed setting with the trowel blade at the pitch angle.
