Abstract: Upon decelating a rotary machine, an electric control circuit energizes an electromagnet. A capacitor charges in the normal mode of operation and beings to discharge upon braking of the machine by a brake device. A relay is energized in the normal mode and utilizing a discharge current from the capacitor, closes its normally open contacts thereby connecting the control circuit to a position sensor. The sensor responds to the machine being at one of its predetermined positions during the energization of the electromagnet to stop it through the brake device after which the relay maintains the control circuit disconnected from the sensor through the normally open contacts. A second relay is energized to change that position where the machine is to stop.

Abstract: An electric motor puts a sewing machine in its normal operation through a clutch. Upon stopping the machine, a transistor and a capacitor fire a thyristor to permit the energization of an electromagnet. This causes the clutch to be partly braked to put the machine in sustained rotation at a low speed. When a position sensor senses the machine being at a selected one of its predetermined positions the electromagnet is deenergized to stop the machine at that selected position through the operation of the brake.

Abstract: A CLUTCH-BRAKE-MOTOR ASSEMBLY COMPRISES AN ELECTRIC MOTOR HAVING A ROTARY OUTPUT SHAFT, A FLYWHEEL CONNECTED TO THE OUTPUT SHAFT, A BRAKE DEVICE POSITIONED IN SPACEDAPART RELATIONSHIP FROM THE FLYWEEL, A CLUTCH PLATE ALTERNATIVELY MOVABLE INTO AND OUT OF ENGAGEMENT WITH THE FLYWHEEL AND THE BRAKE DEVICE, A ROTARY OUTPUT MEMBER CONNECTED TO THE CLUTCH PLATE AND ROTATIONALLY DRIVEN BY THE ELECTRIC MOTOR WHENEVER THE CLUTCH PLATE ENGAGES WITH THE FLYWHEEL, A BIASING SPRING NORMALY BIASING THE CLUTCH PLATE INTO ENGAGEMENT WITH THE BRAKE DEVICE TO BRAKE THE OUTPUT MEMBER AGAINST ROTATIONAL MOVEMENT, AND ACTUATING MEANS FOR SELECTIVELY MOVING THE CLUTCH PLATE OUT OF EN-

GAGEMENT WITH THE BRAKE AND INTO ENGAGEMENT WITH THE FLYWHEEL. THE ACTUATING MEANS COMPRISING A MECHANICAL SYSTEM FOR INTIALLY OVERRIDING THE BIASING SPRING AND STARTING MOVEMENT OF THE CLUTCH PLATE TOWARDS THE FLYWHEEL AND AN ELECTROMAGNETIC SYSTEM ENERGIZABLE IN RESPONSE TO ACTUATION OF THE MECHANICAL SYSTEM FOR ELECTROMAGNETICALLY CONTINUING MOVEMENT OF THE CLUTCH PLATE TOWARDS THE FLYWHEEL. THE MAGNITUDE OF THE ELECTROMAGNETIC OF THE BIASING MOST EQUALS AND CONTERACTS THE MAGNITUDE OF THE BIASING SPRING FORCE AND THEREFORE ONLY A SMALL MECHANICAL FORCE IS REQUIRED ONCE THE ELECTROMAGNETIC SYSTEM IS ENERGIZED.

Abstract: A clutch motor arrangement having a lever for moving the clutch wheel for engaging and disengaging the clutch wheel from a flywheel on an electric motor. The arrangement includes the electromagnets which can be energized independently of the lever. The clutch wheel is engaged with the flywheel for the purpose of adjusting either a position where the associated driven machine is to stop or its speed.

Abstract: Upon stopping an output shaft driven by an electric motor, a clutch is driven into the partly clutched mode of operation through energization of electromagnets. An auxiliary brake disposed on the shaft is also operated by the electromagnets to maintain that mode of operation stable. The electromagnets respond to the associated load being at its predetermined position to be deenergized to stop the shaft and therefore the load at that position.

Abstract: A main clutch engages a flywheel on a motor to drive an output shaft at a high speed. To decelerate the shaft, the main clutch disengages from the flywheel while simultaneously an electromagnet is energized to engage an auxiliary clutch with a flywheel. That clutch drives the main clutch through a brake disc with slip permitted between the main clutch and disc. When the electromagnet is deenergized the auxiliary clutch disengages from the flywheel and engages a brake shoe resulting in its stoppage.

Abstract: A clutch motor for a sewing machine comprising a flywheel on the motor shaft and two concentric clutch wheels connected with one another through reducing gearing and alternatively engageable with the same face of the flywheel. One of the clutch wheels being on an output shaft which is thereby driven at a speed dependent on which clutch wheel is engaged. A lever arrangement makes it possible to stop the sewing machine selectively in different positions as desired.
