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： An endless counting apparatus comprises a first memory for storing a code of a first predetermined number of bits sufficient to represent the maximum value of each coded input expressed according to the binary notation, a second memory for storing an endless-making code of a second predetermined number of bits of higher order than and contiguous to the less and least significant bits stored in the first memory, and a control circuit for adding or subtracting the value of the coded input to or from the contents of the first and second memories depending on the input value to be counted and applying the result of addition or subtraction to the first and second memories. A method for endless counting by such an apparatus comprises clearing the most significant bit of the endless making code stored in the second memory when the code stored in the second memory has attained a value which causes an overflow due to a carry from the contents of the first memory if the carry occurs, and setting the most significant bit of the endless-making code stored in the second memory when the code stored in the second memory has attained a value which causes an underflow due to a borrow from the contents of the first memory if the borrow occurs.

摘要： A motor speed control method and system allow the motor to be accelerated to the steady state in the minimum time even under conditions of varying load torque, varying load inertia and varying power voltage. The motor is controlled by a voltage including a component of proportional term which is a function of a difference between a command speed and a detected speed, and a component of integral term which is summed during an acceleration phase. The acceleration of the motor during the starting process is measured and the integral term is modified basing on the result. The integral term may be memorized so that it is used as the integral term when the subsequent starting phase is completed. The integral term may be obtained from the acceleration and deceleration in the starting process.

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.
