Abstract: A method and an apparatus for adjustment of the rotor angle of an elevator motor (M), in which method: the rotor angle of the elevator motor is measured, the rotor angle is adjusted by using the measured rotor angle value as feedback data, and the rotor angle is measured by means of a pulse emitter (PE) or tachometer connected to the elevator motor. In the method, a disturbance signal (u) is fed into the rotor angle feedback data to produce a change (disturbance) in the rotor angle, the change (disturbance) is compared to the disturbance signal (u), and, on the basis of the comparison, a control signal is generated to adjust the rotor angle.

Abstract: An improved servo system for galvanometers, scanners and similar devices which uses digital processing to increase the dynamic range and provide greater effective resolution. The system provides digital control of a reference point that directly influences the excitation, which in turn directly influences the gain of the circuit. A high and low resolution switching path is provided to optimize dynamic range. Wide angle torque compensation improves uniformity of response at large angular deflections from zero. Improved thermal protection allows safe operation near system thermal limits. A graphical user interface allows adjustment and changes response on the fly for tuning due to input conditions or user control (Figure 2, 100, 110, 130, 140, 150, 160, 170, 180).

The speed selector (10) includes an output shaft (28) which attaches to the adjustment crank shaft (18) of the Reeves drive (11) and a reversible motor (30) having a drive shaft (32) for driving the output shaft (28). Push button switches (82) are provided to selectively energize the motor (30) so that the drive shaft (32) can be manually rotated to a plurality of different rotational positions. A sensing device (34) is provided for sensing the direction and number of revolutions of the drive shaft (32) during positioning thereof and a micro-controller (36) is provided for learning the rotational positions and storing them into selected memory locations (64). Once programmed, the user may select one of the preset speeds on a key pad (66) and the device will automatically control the motor (30) to position the drive shaft (32) in the desired position thereby automatically adjusting the Reeves drive (11) to a desired speed.

Abstract: A position measurement system includes position error circuitry (PEC) (52) that responds to periodically provided actual position information and a computed position to provide correction information, and a position synthesizer (55) which responds to the correction information to provide the computed position. The computed position information is fed back to the PEC. The position synthesizer establishes a rate of change of the computed position based on the correction information in a manner tending to make the computed position track the actual position. The position synthesizer updates the computed position many times for each time that the actual position information is provided to the PEC, and thus provides much more continuous position information.
