A brushless motor assembly includes a housing, a cover assembly, an insert, and a sensor assembly. The housing is disposed about a motor. The cover assembly is disposed on the housing and has a base and a connecting portion. The connecting portion defines a connecting region. The insert has a first insert surface and a second insert surface disposed opposite the first insert surface, each extending between a first insert end and a second insert end. The sensor assembly is disposed on the second insert surface.

This present disclosure relates to a motor arrangement for controlling pilot valves having at least three motors, having at least one stator each and at least one rotor each, wherein the motors are provided at a common rotating shaft, with each motor being coupled to the rotating shaft via at least one respective mechanical coupling.

In an electric driving apparatus, a sensor magnet is fixed to a first end portion of a rotary shaft of a motor. A sensor device includes a rotation sensor that detects a magnetic field generated by the sensor magnet. The rotation sensor opposes the sensor magnet in an axial direction of the rotary shaft. A control unit mounted on the motor includes an inverter circuit that is connected to an armature winding of the motor via a plurality of feeder wires. The inverter circuit is disposed in a position further from the sensor magnet than the rotation sensor in the axial direction of the rotary shaft. A shield plate formed from a magnetic material is disposed between the rotation sensor and the inverter circuit.

A system for estimating parameters of an electromagnetic load may include an input for receiving an input excitation signal to the electromagnetic load, a broadband content estimator that identifies at least one portion of the input excitation signal having broadband content, and a parameter estimator that uses the at least one portion of the input excitation signal to estimate and output one or more parameters of the electromagnetic load.

A location and retention component is provided for positively locating an overspeed guard and retaining a centrifugal actuator at an optimum positional relationship relative to each other. The system includes a first and second retention element removably engagable to the output shaft of a motor and axially fixable to the shaft at corresponding locations to maintain the optimum positional relationship. The first retention element serves as a positive stop for assembling the overspeed guard on the motor shaft, while the second retention element ensures that the centrifugal actuator is properly placed within the overspeed guard.
