    摘要： An electrical stepper motor system is provided in which a microcomputer controlled driver monitors the real time operating parameters of the stepper motor. The driver is controlled by the microcomputer to keep the real time operating parameters of the motor in a range that is governed by limiting parameters. The limiting parameters are determined by the microcomputer on a moment by moment basis in response to changes in certain conditions occurring within the stepper motor, as well as in the outside operating environment. The microcomputer compares the microcomputer determined safe operating parameters with any user stipulated operating parameters, stored in the storage means of the microcomputer, to determine limiting parameters on a moment by moment basis. An encoder senses the position and velocity of the motor and provides appropriate status signals to enable the driver to compensate for position and velocity errors of the stepper motor. An indexer is also provided which provides the driver with pulses that determine the distance, speed and direction of a move. In the illustrative embodiment, the driver, microcomputer, indexer, power supply and encoder circuitry are hybridized on at least one hybrid circuit, each circuit being attached to a heat sinking system, potted in a series of thermally conductive and EMI/RF insulating compounds, and are enclosed in a metallic enclosure that is shielded from outside electrical noise, with the enclosure being directly coupled to the back of the stepper motor to form a compact, unitary device.

    摘要： Adaptive control system for a numerical control machine tool like a lathe with a control program which contains the information about the outline of raw workpiece prior to blocks commanding the desired outline of the manufactured workpiece. The length of movements of the bit of said machine towards the direction of the center of said workpiece at the beginning of the cutting is controlled in a manner such that the cutting depth of said bit is shorter than the length of the cutting edge of said bit, and the load of said machine in the cutting operation is controlled so as to be equal to the upper limit of the allowable load. The system of the present invention provides prevention of damage to the bit, a shorter manufacturing time and improved operation efficiency of said machine.
