摘要： A speed control device for an electric motor fed by a direct voltage source, the device comprising a controlled switch by which the motor voltage is alternately switched on and off under the control of a modulated switching pulse sequence. The switching frequency is higher than the frequency corresponding to the time constant of the electric motor. The switched motor voltage is regulated to a voltage set value corresponding to a desired motor speed by influencing the modulated switching pulse sequence.

摘要： A system for driving a blower of a heating, ventilating, and/or air conditioning (HVAC) system. The blower discharges heated or cooled air to a space for conditioning the air in the space by changing its temperature. A motor drives the blower at a speed or torque defined by a motor control signal thereby to control air flow rate of the HVAC system. The system includes a temperature sensor generating a temperature signal representative of the temperature of the air discharged to the space by the blower. In response to the temperature signal, a control circuit generates the motor control signal to cause the motor to operate at a minimum speed or torque until the temperature of the discharged air as represented by the temperature signal reaches a reference temperature. After the temperature of the discharged air reaches the reference temperature, the control circuit generates the motor control signal to control the motor speed or torque as a function of the difference between the temperature of the discharged air and the reference temperature whereby the air flow rate of the HVAC system is increased as the temperature difference increases.

摘要： A system which drives a component of a heating, ventilating, and/or air conditioning (HVAC) system in response to a system control signal such as a temperature signal provided by a thermostat. The system includes a motor having a stationary assembly and a rotatable assembly. The rotatable assembly is in magnetic coupling relation to the stationary assembly and is in driving relation to the component. The motor drives the component in response to a control signal generated by a microprocessor. The microprocessor is responsive to parameters representative of the system and to the system control signal. The parameters are stored in a memory and are defined in response to a parameter select signal. The control signal provided by the microprocessor controls the speed and torque of the motor. The system further includes an instruction memory for storing instructions controlling the operation of the microprocessor.

摘要： A system (20) for controlling deceleration of a motor (22) during an abrupt power-off condition includes a processor (40), a motor control circuit (50), and a secondary power source (70). During normal power-on operation and based on currently prevailing operation parameters, processor (40) routinely generates a contingent motor-governing deceleration signal for potential use in governing motor (22) should the power-off condition occur. In response to the occurrence of a power-off condition, motor control circuit (50) controls motor (22) in accordance with the contingent motor-governing deceleration signal to achieve orderly deceleration. Secondary power supply circuit (70) provides power to motor control circuit (50) during the power-off condition.

摘要： An apparatus and method of protecting a centrifuge from rotor overspeed and resultant mishap by computation of the rotor moment of inertia is disclosed. In the preferred embodiment, a centrifuge is driven by a rotor mounted on a shaft which shaft is in turn driven by a constant current motor. A tachometer for detecting angular velocity of the drive shaft is used. A desired and ultimate centrifuge operating speed is selected by the operator. The times at which the rotor passes through discrete speeds are recorded and from the time difference the moment of inertia is computed. The moment of inertia can thereafter be utilized to discretely identify or "finger print" rotors to disqualify certain rotors from use in particular centrifuge protocols and establish gross limits of centrifuge operating speed.

摘要： In a device for regulating the speed of a vehicle, particularly an automotive vehicle, having an electronic regulator, at least one first storage for the storing of a first speed desired-value signal as well as a control arrangement for the storage are provided. In the regulator, a speed actual-value signal is compared with the speed desired-value signal and a corresponding setting signal is produced which actuates a setting member (13). There is also connected to the regulator an operating device (16) which comprises at least one button (19 or 20) for setting the storage to the speed desired-value signal, one button (17) for disconnecting the regulation as well as a restart button (18) for reactivating the regulation. Within the regulator there is provided a second storage (5) for storing a second speed desired-value signal which forms a so-called stack together with the first storage (4). The stack of the two storages can be so controlled by the control arrangement (16) that at suitable times the first or the second speed desired-value signal can be set in the first storage and in this way the previously stored speed desired-value signal can also be used for the regulation at a desired later point in time.

摘要： A control unit for model vehicles, such as model railway trains, model automobiles, etc. For independent operation of several model vehicles on a common electric circuit, it is known to allocate to each model vehicle a receiver coded in relation with hardware and controlled according to a binary word consisting of an address part and a data part. Control units of this type, however, have the disadvantage that they cannot be operated on analog electric circuits. With the invention, a control unit is proposed which independently switches off the digital control logic in the case of a change of the model vehicle from a digital trackage to an analog trackage, and enables operation of the model vehicle via an amplitude-controlled or pulse width-controlled analog signal.

摘要： A circuit for applying current pulsations of opposed polarity to an inductive load wherein the net current in the load is the difference in the magnitude of the pulsations. A capacitance is connected across the inductive load to permit the buildup of a net current. Circulating currents in the capacitance can be restricted by inductance or resistance in series between the source of pulsations and the capacitance.
