摘要： An apparatus and a method for changing velocity of a hybrid induction motor are provided to improve operation efficiency of the hybrid induction motor, by changing the velocity of the hybrid induction motor by changing the amplitude of an operation capacitance. A hybrid induction motor is started by the start capacitance of a start capacitor(Cs), and is operated by operation capacitance of an operation capacitor(Cr) when the hybrid induction motor reaches a synchronous velocity. In the hybrid induction motor, a number of velocity-changing capacitors(C1,C2) are connected by the operation capacitor in parallel and changes the velocity of the hybrid induction motor by increasing the operation capacitance, by a control signal. A control unit(100) analyzes a user command, and outputs the control signal to change the velocity of the hybrid induction motor on the ground of the analysis result.

摘要： A permanent split capacitor (PSC) motor includes a stator defining an axis of rotation and a rotor disposed adjacent the stator. The stator includes a start winding, a capacitor electrically coupled in series with the start winding, a first plurality of windings, and a second plurality of windings. At least one winding of the first plurality of windings is energized in parallel with at least one winding of the second plurality of windings at a first voltage and in series with the at least one winding of the second plurality of windings at a second voltage. The first and second pluralities of windings are energized to produce a plurality of motor speeds. The rotor rotates relative to the stator about the axis of rotation at a selected one of the plurality of motor speeds induced at least partially by a magnetic output of the windings of the stator.

摘要： An electronic system is disclosed for controlling both the ascendant and the descendant speed in vertical machines such as cranes, elevators, etc., in which it is required to lift different loads in a regulated and self-controlled manner, laying aside the traditional mechanical and/or pneumatic control systems. Such control is achieved by virtue of the voltages included in the secondary of the motors of the wound rotor type used in such machines to lift or to bring down different loads, which may vary within a wide range from practically the vacuum to an overload, being possible by such control to select and to maintain both the ascendant and the descendant speed of the load.

摘要： A motor speed control system in which the rotor output frequency is filtered to remove slot noise and applied to one or more frequency discriminator units (FDU's) which provide control signals to operate relays which control contactors in a conventional motor controller having rotor speed control resistances. Each FDU compares the input frequency with its own setpoint frequency and operates to change rotor circuit resistance if the input frequency differs from the setpoint by a predetermined amount. The rotor signal is separated into two rectangular wave signals, one of which triggers a monostable circuit. The Q and Q monostable outputs are compared with the input in logic circuit means which produces a relay driving output under specified signal time-overlap conditions. A feedback signal changes the duty cycle of the monostable when the output is provided, thereby establishing a frequency "dead band" bracketing the setpoint. A "low signal" circuit insures a predetermined state of the FDU under low level or zero frequency conditions. The output operation can be reversed for counter torque motor deceleration applications.

摘要： A circuit for effecting dynamic braking of a wound rotor polyphase induction motor comprises rectifier means for rectifying the output of the rotor and switch means which disconnect the stator from the mains supply and connect the rectified rotor output through a d.c. chopper to one or more phase windings of the stator to effect dynamic braking of the motor. The level of direct current in the stator phase windings, and hence the degree of braking, is controlled by the d.c. chopper, which may also be employed to control the driving speed of the motor.

摘要： A motor control system for controlling the speed of a threephase wound-rotor induction-type electric motor. Silicon controlled rectifiers are connected in circuit with the rotor windings of the motor for controlling the current flow therein. A control circuit is connected to the gate electrode of each of the silicon controlled rectifiers for firing same. These control circuits are responsive to the rotor winding voltages for determining the phase angles at which the silicon controlled rectifiers are fired. This control action acts to hold the motor speed constant under varying load conditions. Adjustable bias circuit means are connected to each of the control circuits for changing the basic operating speed of the motor.
