摘要： Rotary encoders for use with trolling motors are disclosed. An example rotary encoder includes a housing defining an aperture and a linear guide and an input sleeve to extend through the aperture. The input sleeve includes an exterior guide to be engaged and followed by a shuttle to enable rotary position information to be obtained from the input sleeve. The shuttle is movably coupled within the linear guide. The shuttle is biased to engage a central portion of the exterior guide if rotation of the input sleeve moves the shuttle past first or second ends of the groove to prevent the rotary encoder from being damaged by over-rotation of the input sleeve.

摘要： A servo motor control apparatus has a feedback loop. When an oscillation detection signal indicates no detection of oscillation, a parameter operating section gives an updating section an operational instruction to set a control parameter in accordance with a supplied set value. When the oscillation detection signal indicates detection of oscillation, the parameter operating section gives the updating section an operational instruction to set such a control parameter as to narrow a frequency band width of the feedback loop.

摘要： A method for determining a commutation offset for a mover (250A) of a mover assembly (220C) that moves and positions a stage (220A) relative to a stage base (220B) includes controlling the mover assembly (220C) in a closed loop fashion to maintain the position of the stage (220A) along a first axis and along a second axis with the stage (220A) levitated above the stage base (220B). The method also includes the steps of (i) directing current to a coil array (240) of the mover assembly (220C) so that the mover assembly (220C) imparts a disturbance on the stage (220A); and (ii) evaluating one or more forces generated by the mover assembly (220C) as a result of the disturbance on the stage (220A) created by the mover (250A). Further, a method for generating a compensation map (1402) includes sequentially directing a plurality of excitation signals to the control of the mover assembly (220C) and determining the control commands that result from the plurality of excitation signals.

摘要： A feedback switching device and a method allow a drive control loop for a servo motor to actively switch the feedback mode in accordance with the rotating speed of the servo motor. When the servo motor is under a high speed operation, a sensorless position estimation feedback technology is used as the feedback mode; on the other hand, when the servo motor is under a low speed operation, the switching mode is automatically switched to a position sensing feedback technology. Therefore, the development needs for multi-function, high performance and low cost in the field of the servo motor control are met, and the conventional problem is solved that, when being applied to a servo driving system having a wide speed range, the single use of the position sensing feedback technology or the sensorless position estimation feedback technology fails to satisfy the application for a wide speed range.

摘要： A control device for a travel motor mounted to a vehicle has a resolver which works as a rotation-angle sensor. The control device has a RDC which calculates a rotation-angle output value φ based on rotation detection signals Sa, Sb transferred from the resolver. The control device supplies electric power to the travel motor based on the rotation angle output value φ. The RDC calculates “sin(θ−φ)” as an error deviation ε based on the signals Sa and Sb and the rotation-angle output value φ. The RDC calculates an angular acceleration by multiplying the error deviation ε with a gain (=Ka·Kb), and integrates the angular acceleration two times in order to obtain a next rotation-angle output value. A gain control part of the RDC decreases the gain when the judgment means judges that the travel motor rotates at a constant rotation speed.
