    • Disclosed herein are a motor control circuits and a control system comprising the motor control circuits. Each motor control circuit comprises a pulse generation counter (110) for counting a clock and generating control pulses, a pulse counter (119 to 122, 126) for counting the control pulses, a rate data conversion ROM (103) for converting the speed data to a count value used in the pulse generation section, first holding section (104, 105) section for holding at least the information concerning the upper and lower limits of the speed, second holding section (122, 123) for holding at least the information concerning the acceleration and deceleration speeds, and speed change section (107) for increasing or decreasing the speed data gradually by counting the count of the pulse counting section from the lower to the upper limit of the speed held in the first holding section with a value corresponding to the acceleration or deceleration speed held in the second holding section, and giving the instructions of rewriting each value and of starting and stopping the operation corresponding to a predetermined command from the main control section (1).

    • A speed control system for an a.c. electric motor (1) comprises a microcomputer (6) to an interrupt signal input ( INT /TO) of which are coupled the outputs of a detector (10) for zero-crossings in the a.c. supply and a tachogenerator (11) connected to 'the motor. The microcomputer supplies firing pulses to a triac (2), included in series with the motor, in response to an overflow of a clocked counter (CT), this counter being suitably preloaded at each zero-crossing. The counter is read each time a tachogenerator pulse occurs and the time which this reading indicates has elapsed since the immediately preceding zero-crossing is stored. A record is also kept in a register (ZCSLTA) of how many zero-crossings occur between each tachogenerator pulse and the next and from this and the stored times relating to the relevant pulses the period of the tachogenerator pulses and hence the actual speed of the motor is calculated. The preloading value for the counter is calculated from this and the required speed.
