Abstract

Vynález rieši obvodové zapojenie brzdy indukčného motora kde sa pre zabrzdenie využívá výboj nabitého kondenzátora do vinutia motora.The invention solves the circuit connection of an induction motor brake where the discharge of a charged capacitor into the motor winding is used for braking.

Description

Servos and other devices where the engine must be stopped in a short time are used electrically or pneumatically operated mechanical brakes, electromagnetic clutches, unidirectional unidirectional current and the more well-known methods and their combinations. parts, their delayed reaction and, in addition, the relative long time after complete engine shutdown.

The invention and the present invention relates to a pulse brake of an induction motor actuated by a sprayer, the first anode of which is connected to a first pole of a supply voltage source and a second anode to a second motor outlet. The first motor outlet is connected to a second field of the AC source.

The essence of the invention is that an anode of the diode is connected to the first pole of the voltage source, whose cathode is connected via a capacitor to the second pole of the AC source and to the first motor and simultaneously via a semiconductor switch implemented by, for example, a emitter or triac or transistor or a transistor together with a series diode on the second motor outlet and anodutriac species.

The wiring is described in the attached diagram. The motor M is controlled by a trolley with a command input g1. The first triac anode A1 is a

the second outlet of the motor M, the first outlet of the engine is connected and the second of the supply 2 of the Uat supply. A diode D anode is connected to the first pole 1 of the intermediate voltage source, the cathode of which is connected to the second pole of the AC voltage source and to the first outlet of the motor M, and simultaneously via a semiconductor switch S, e.g. a triac, or a transistor, or a transistor together with a series-connected diode feeds the m2 of the motor M and the types of the triode anode A2. 238 453

Capacitor C is via a diode D permanently energized by unidirectional current from an alternating voltage source Ust. After the command is terminated, select the triac switch X via input g., The spacecontrolled semiconductor switch S, discharge the capacitor charge to the motor winding. With small motors, this solution allows accurate measuring of the movement of the self-mechanic using conventional motors. The connection is equally applicable to three-phase motors, where the capacitor circuit is used independently in either one, two, or all three phases.
