摘要： A circuit (18) for speed monitoring of an electric motor (14) comprises a circuit (106) for generating a time-frame signal, a circuit (106) for receiving a first signal (V g ) from a chopper driver circuit (16) designed to drive the electric motor (14), a circuit (106) for detecting chopper pulses (103) in the first signal (V g ), a pulse counter (112), and a circuit (115) for at least one of outputting and evaluating a state of the pulse counter, after the inactive state of the time-frame has been indicated. The time-frame signal indicates when a time-frame of predefined length changes from an inactive state to an active state and indicates when the time-frame changes back from the active state to the inactive state. The pulse counter (112) is designed to count the detected chopper pulses (103) while the active state is indicated by the circuit (106) for generating the time-frame signal.

摘要： A system for driving a stepper motor and adapting characteristic parameters of the stepper motor comprising a driver sub-system, responsive to control signals, for transferring power to the stepper motor. A power supply provides a driver current to the driver sub-system. A current detection device, responsive to the driver current, generates a digital feedback signal representative of the driver current. A digital processor, responsive to the digital feedback signal, generates the control signals. The digital processor is further responsive to a software algorithm to generate the control signals. These control signals provide functionality comprising detecting forces applied by the stepper motor to a load preventing a stall condition, adapting stepper motor speed and torque parameters, and limiting applied forces and driver current.

摘要： The invention refers to automatics and electrotechnics and can be used for bipolar control of four-phase step motor acting in the electrical drives of the executive mechanisms of robots, machine tool control systems and computer peripherals. The purpose of the invention is broadening of functional possibilities and spheres of implementation through ensuring 12-, 6-, 4- and 3-tact modes of phase, as well as increase in accuracy, smoothness and uniformity of its rotation. One of the significant peculiarities of the proposed method and the device is that within all phase commutation modes, the positions of torque vectors do not coincide with the poles of the four-phase step motor. This allows to avoid the possible influence of non-linearities of the motor magnet system (e.g. influence of saturation) and, thus, increase to a higher extent the accuracy of adjustment of single steps.

摘要： The invention provides a method and system for calibrating an instrument pointer driven by an electric motor against a mechanical stop without using feedback control. According to the invention, the system for calibrating said instrument pointer comprises a pointer (8) engageable with the electric motor (2) including an intermediate gear (3) for driving the pointer (8). A stop means (5) is positioned at a desired reference point where, in a first powered state, the motor (2) is accelerated at a maximum torque for a first predetermined radial distance to move said pointer (8) towards a position whereat said stop means (5) is engaged. The motor (2) is then re-accelerated at a reduced torque for a second predetermined radial distance, whereby the pointer (3) is caused to be moved and held against the stop means (5).
