摘要： A method of controlling motor speed. The motor speed control apparatus includes an encoder in mechanical association with the motor. The encoder has one channel providing an encoder signal having a rising and falling state transition for each period of the encoder signal. The periodic frequency of the state transitions are used to precisely measure instantaneous motor speed. A comparitor then compares the periodic frequency with a predetermined motor speed to provide an error signal, representative of the difference. A feedback control system affects the motor speed dependent on the error signals. In a further embodiment, the encoder includes two channels and four state transitions.

摘要： A high resolution speed control for a DC or BLDC phase-locked-loop (PLL) motor is provided. A phase accumulator (38) sends a time varying frequency reference to the PLL (42) input, where the average frequency sets the motor speed with a high degree of accuracy. A post divider (40) is used to reduce the number of circuits required to implement the function.

摘要： Synchronization of the output of an internally-driven VCO to an exterior clock signal is obtained by using the exterior clock signal to re-start the VCO at every exterior clock pulse, until the pre-set VCO frequency is reached. At that point, the re-starting of the VCO ceases, and the VCO locks onto the internal signal it is designed to track. One application of this circuit is for enabling a smooth transition between open-loop, ramp-up of a polyphase DC motor, enclosed-loop operation of the motor to closed loop operation. Implementation of the circuit described phase-synchronizes the output of a phase-switching PLL loop, which is tracking the back emf of the motor, to the external clock used for motor ramp-up, so that there is no "jolt" in the motor at the transition from open-loop to closed-loop operation of the motor.

摘要： @ The speed of a DC motor is controlled by a servo which includes a digital phase lock loop. The motor drives a tachometer whose pulse (22) frequency is low relative to the frequency of a clock - (21). The clock continuously drives a counter (200) whose ever increasing number content is gated to a data latch (26) upon the occurrence of each successive tachometer pulse, thus this data latch contains a first time-number of ever increasing magnitude. A second data latch (24) contains a second number. The difference in magnitude of two consecutive time-numbers is indicative of motor speed. Initially, this second number is set to contain a reference number (REF) which is equal in magnitude to the number of clock pulses which will occur between adjacent tachometer pulses when the motor is running at desired speed. A pair of limit numbers - (RANGEL and RANGEH) are provided to define the upper and lower limits of servo saturation. The difference between the first number and the second number is detected upon the occurrence of each tachometer pulse to generate a third or difference number (ERRA). This difference number is compared to the two limit numbers to determine if the servo is in saturation. If it is not in saturation, the second number is reset to a value which is equal to the old value plus the reference number. If the servo is in saturation, the second number is reset to a number which is a function of the first number, the reference number, and that limit number which is associated with the particular mode of saturation.

摘要： A digital capstan servo circuit controls the rotation of a capstan motor used for sending a recording medium of a recording apparatus having a recording circuit for recording a plurality of pilot signals instead of CTL signals used for a tracking servo of the capstan motor in a reproducing mode. The pilot signals have different frequencies respectively and are recorded under being mixed with a video signal on video tracks. In the recording mode, rotation speed information obtained from a counter (3) of which a counting value is latched by a latch pulse produced by a generator (27) from the FG signals which are generated synchronously with the rotation of the capstan motor and rotation phase information obtained from the counter (3) of which a counting value is latched by a latch pulse produced by a generator (28) from the output of an oscillator, an output signal of the oscillator having the same frequency as that of but a different phase from as that of the FG signals, are mixed to be a control signal of the capstan motor.
