An example apparatus includes a controller operatively coupled to an electric actuator via a network. The controller is configured to obtain torque curve data over the network from the electric actuator, the torque curve data being associated with actuation of an electric motor of the electric actuator, the actuation to cause a flow control member of a motor-operated valve to move, the flow control member being mechanically coupled to the electric motor and being movable between an open position and a closed position. The controller is configured to determine an area under a torque curve based on the torque curve data, determine a variance between the area under the torque curve and an area under a reference curve, and generate a first control signal indicating that the electric actuator is healthy when it is determined that the variance does not exceed the variance threshold.

According to one aspect of the present disclosure, an electric motor for a laundry appliance includes a first stator having a central axis. A first rotor is in electromagnetic communication with the first stator and is rotationally operable about the central axis. A second stator is aligned with the central axis. A second rotor is in electromagnetic communication with the second stator and is rotationally operable about the central axis. The first and second stators are positioned within a common motor cavity of an outer housing. A controller regulates a first electrical current to the first stator and a second electrical current to the second stator. The controller includes a torque discrimination module for monitoring an output torque of at least the first rotor.

A power module of an electric assisted bicycle is disclosed and includes a pedal shaft, a gear-plate-output shaft, a reducer, a motor, a first sensor, a housing, a second sensor and a driving controller. The gear-plate-output, a reducer-output shaft and a reducer-fixed shaft of the reducer are disposed in parallel and sleeved on the pedal shaft concentrically. The motor drives the gear-plate-output shaft to rotate. The first sensor is disposed on the reducer-fixed shaft for sensing a first torque of the reducer-output shaft acting on the reducer-fixed shaft. The reducer-fixed shaft is connected to the housing. A frameset-fastening component protrudes outwardly from the housing, and is configured to fix the power module on the frameset. The second sensor is disposed on the frameset-fastening component for sensing a second torque of the power module acting on the frameset. The driving controller controls the motor in accordance with the second torque and the first torque.
