摘要： A pulse width control apparatus and method for controlling motor speed wherein the number of pulses relating to more speed feedback data is counted so as to control the speed of the motor in accordance with a speed command data and a pulse width modulation signal based on the counted number of pulses. A free-running hardware timer and a soft-timer on a program controlled by an instruction execution time of a microcomputer are arranged so that ON-time data and OFF-time data of the pulse width modulation signal are selectively set in one and the other of the hardware and soft-timers in dependence on values of the ON and OFF times, respectively. The ON and OFF states of the pulse width modulation signal are changed when the contents of the hardware and soft-timers reach predetermined values so as to control the pulse width thereof.

摘要： A rotary cylinder apparatus comprises a rotary drum mounted thereon with a magnetic head, a brushless motor for driving the rotary drum, a stationary drum housing the brushless motor and which is disposed opposing the rotary drum, and a revolution-rate detector for detecting the number of revolutions of the rotary drum. The brushless motor comprises a permanent magnet rotor connected to the rotary drum, a driving coil mounted on the stationary drum, and a position detector for detecting the position of the permanent magnet rotor in order to control current to be supplied to the driving coil. The detecting coil of the revolution-rate detector and the brushless motor are housed in the stationary drum and wiring of the driving coil and revolution-rate detecting coil is performed on a common wiring board. Thus, the driving section of the rotary cylinder apparatus is small-sized and made light in weight, and the number of processes of assembling the rotary cylinder apparatus can be decreased.

摘要： A protection apparatus for an electric sewing machine having a drive mechanism for driving the sewing machine by a motor comprises a speed detecting means for detecting a rotational speed of a shaft of the sewing machine, comparator means for comparing a rotational speed signal of the shaft of the sewing machine from the speed detecting means with an externally applied speed command signal indicative of a predetermined rotational speed of the sewing machine to determine from the comparison result whether the sewing machine is in a fault state, and invalidation means for deactivating the drive mechanism when the fault state of the sewing machine is determined by the comparison means. The protection apparatus detects the rotation of the shaft of the sewing machine while an operation command for the sewing machine is being inputted to early-detect an overload condition of the sewing machine. When an overload condition is detected, the motor and hence the sewing machine is stopped to prevent the damage of the motor.
