摘要： The present invention provides method and apparatus to control a plurality of DC motors each having an encoder by a sole microcomputer. The actual rotating speed of each DC motor is detected in response to the signal from the encoder. A pulse width of a voltage which is applied to each motor is controlled due to the deviation between the actual speed and a preset speed. The output signals from the encoders regarding a specific DC motor to the other DC motor are sequentially selected by a selection signal, thereby controlling the speed measurements and calculations regarding a plurality of DC motors and the duties of electric powers which are applied to the DC motors.

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 large number of teeth are formed on the outer circumference of a rotor. A stator is disposed around the rotor. The stator has multiple magnetic poles whose number is n times the number of phases. Each pole has formed on its surface a plurality of teeth at a pitch equal to the rotor tooth pitch. The teeth mounted on the adjacent magnetic poles are selected to deviate in pitch one-half or thereabout from the rotor teeth and the adjacent poles are to be opposite phases from each other.
