摘要： According to one example there is provided a method of adjusting a support structure. The method comprises obtaining a reference orientation of the support structure when the support structure is positioned in a reference position. The height of the support structure is adjusted to a predetermined position and the orientation of the support structure is adjusted such that the orientation of the support structure when in the predetermined position is substantially the same as the reference orientation.

摘要： A CPU obtains a difference between a data number at timing when an ENC0 signal or an ENC1 signal changes in a case where there is no follow-up delay of a rotor relative to a voltage signal applied to an A-phase coil and a B-phase coil and a data number at timing when the ENC0 signal or the ENC1 signal changes in a case where there is a follow-up delay of the rotor relative to the voltage signal applied to the A-phase coil and the B-phase coil. Then, the CPU controls the voltage signal applied to the A-phase coil and the B-phase coil based on the obtained difference.

摘要： A circuit for controlling a load current through a coil is connected to an output port of a transistor H-bridge that includes two low side transistors and two high side transistors. A current sense circuit is coupled to the H-bridge and configured to provide a representation of the load current provided by the output port. A current regulator is configured to generate a modulated signal dependent on the representation of the load current and a current set-point. The modulated signal has a duty-cycle. A gate control logic drives the individual transistors of the H-bridge on and off in accordance with the modulated signal. A direction signal provides the load current to the coil. The direction signal determines the direction of the load current. An over current detection circuit is coupled to each individual transistor and is configured to signal an over-current by providing an active over-current failure signal when a transistor current through the respective transistor exceeds a respective maximum value.

摘要： When a stepping motor is driven to rotate by a main driving pulse, if an induced signal exceeding a reference threshold voltage is detected only in a third segment, a pulse down operation is performed, and the main driving pulse is not changed when the same is detected in at least a first and the third segments. When it is detected only in a second and the third segments, a rank-up is performed without performing the driving by a correction drive pulse and, when it is not detected in at least the third segment, the rank up operation is performed after the driving by the correction driving pulse.

摘要： A system for calculating control pulse duration for optimal stepper motor performance. Duration of control pulses to a stepper motor is increased until stepper motor function begins. The duration of control pulses continues to be increased. It is determined whether stepper motor failure is detected. In response to detecting a failure, the duration of control pulses at the time of the failure is recorded. The duration of control pulses is decreased until stepper motor function is restored. The duration of control pulses continues to be decreased. It is determined whether a second failure is detected. In response to detecting a second failure, the duration of control pulses at the time of the second failure is recorded. A control pulse duration is calculated that optimizes performance of the stepper motor using recorded control pulse duration data. The calculated control pulse duration is applied to the stepper motor.

摘要： An electrical control system for a rotatable wheel cover assembly is presented, the system including a controller assembly comprising processors for controlling the relative motion of a wheel cover rotatably mounted to a wheel frame of a vehicle. The controller assembly outputs a first signal to motor drivers, which are mounted within the vehicle separated from the wheel cover, the motor drivers passing a first drive frequency to motor leads for open loop control of the speed of the motors that drive the wheel cover. The electrical control system provides power from an inboard side of the wheel frame to an outboard side via a slip ring assembly having connector assemblies passing through the wheel frame for controlling motion of the wheel cover. The wheel cover is mounted to a shaft of the motor, wherein the motor is mounted coaxially with the wheel frame.
