Title: Drive control system for stepping motors
IPC: H02P8/12
Filed: 1971-09-08
Abstract: 1369057 Control of stepping motors TOKAI RIKA DENKI SEISAKUSHO KK 8 Sept 1971 [9 Sept 1970] 41878/71 Heading H2J A conventional stepping motor, having two exciting coils which respectively magnetize polepieces co-operating with permanent magnets carried by the rotor, Figs. 1 and 2 (not shown), and wherein the two sets of polepieces and magnets are arranged to be 90 electrical degrees out of step, is energized to provide a uniform torque by a control system which alternately energizes one coil and both coils and which increases the coil current in the single excitation state relative to the current per coil in the double excitation state. Each coil A, B is controlled by a respective transistor-diode-resistor circuit N1, N2 having two transistors alternately switched on and off by NOR gates Gm1, Gm3 and Gm2, Gm4, whose inputs are derived from NOR gates Gk1 ... Gk4 and Gl5, Gl6, Gl11, Gl12 which, with the other NOR gates shown in Fig. 13, form two reversible binary flip-flop circuits K, L. These are controlled by a binary stepping input at terminal P, by a reset pulse P 1 and by a trigger pulse P2 which is applied to either the terminal CW or the terminal CCW according to whether forward or reverse direction of motor rotation is desired. The gates Gk1 ... Gk4 also form inputs to a current variation circuit I having two transistors, the second of which shunts a resistor so that switching on of the transistors provides the increase in the coil current during the single excitation state. In a typical stepping operation, the sequential application of 0, 1 inputs to the terminal P produces appropriate outputs from the gates supplying circuit I and gates Gml ... Gm4, so that the latter produce outputs singly or in pairs whereby the coils are energized in the manner shown in Fig. 8. By ensuring that the coil current in the single excitation state is approximately #2 times the current per coil in the double excitation state, a uniform torque for both states is obtained and the rotor step angle per input pulse can be reduced compared to that obtainable in a prior art control system. Operation of the motor for a typical stepping sequence, Fig. 9 (not shown), is compared with the operation when controlled by the prior art system, Figs. 4 to 7 (not shown). Operation of the binary flip-flop circuit is described, Figs. 11 and 12 (not shown).
