摘要： A low inertia, speed variable induction motor comprises a frame, a stator fixedly placed in the frame, a yoke fixedly placed in the frame in opposition to the stator with a predetermined gap and a cup-shaped rotor which is inserted into the gap and is fixedly mounted on an output shaft supported in the frame in a freely rotatable manner. Rotating magnetic field is produced in the gap by the stator and the yoke to generate a rotational torque of the cup-shaped rotor. The cup-shaped rotor is formed of a material or materials having a hysteresis characteristic and an eddy current producing characteristic to obtain a large torque.

摘要： A motor has an electromagnetic brake which is connected to the output shaft to brake the rotation of the output shaft, whereby the driving body can be forcibly braked with excellent stopping response.A fan for forcibly cooling the inside of the motor is enclosed in the casing, whereby temperature rises can be prevented by ventilation.A bracket for supporting the iron core of the brake coil is made of a non-magnetic material, whereby the leaked magnetic flux passing through the bearing fixed on the bracket can be prevented, and consequent damage to the bearing heated by the eddy current can be prevented.The stator can be a stator having windings used in a conventional induction motor, and the rotor is a cup type rotor having a simple structure extended in the axial direction. Accordingly, the structure is simple, and the size of the motor in the radial direction can be reduced.

摘要： The disclosure describes an electromagnetic clutch/brake device which prevents undesired vibration of a rotary brake mounted on an ouput shaft so as to be slidable in its axial direction. For this purpose, the rotary brake is made unbalanced in weight in a specified direction with respect to its revolution center and a driven rotary body mounted on the output shaft and subjected to rotational force from the output shaft is made unbalanced in weight in a specified direction with respect to its revolution center. The driven rotary body and the rotary brake are fitted to the output shaft so that they are in a balanced condition when the shaft is driven.

摘要： A movable disc for a friction type electromagnetic clutch/brake is designed for preventing the production of grating sounds from the movable disc. The movable disc includes a rotary armature being movable in a predetermined direction by the application of electromagnetic force, a friction material stuck onto one side surface of the rotary armature, an elastic member supported on one side surface of the rotary armature to the side opposite to the friction material, a face plate fitted to the rotary armature so as to urge the elastic member to the rotary armature. Perforations are formed in the face plate to reduce its mass and the surface area contacting to the elastic member thereby attaining a rapid start up and good periodic damping characteristic.
