STEPPING MOTOR EXCITING SYSTEM |
摘要 |
A stepping motor exciting system in which the excitation current is set at one of four stepwise values. When the motor is to be driven in a stepwise manner, the excitation current is in the form of a pseudo-trapezoidal wave which is derived in terms of two of possible four values. When the motor is to be driven in a linear manner, the excitation current is in the form of a pseudo-sinusoidal wave which is derived in terms of all four possible values. A ROM stores these sequences of excitation currents and controls the exciting system in accordance with the driving mode desired. |
