Asynchronous Induction Clutches/Brakes TRIZ Cases
- Electrodynamic Contactless Braking With Alternating Eddy-Current Fields
Alternating electromagnet orientations induce eddy-current drag for contactless braking, reducing wear while maintaining controllable resistance.
- Eddy Current Brake for Crusher Roller Wear-Free Restraint
Magnetic braking yokes and a conductive disc restrain crusher roller rotation without friction, reducing brake wear and actuator complexity.
- Controlled Descent Brake Using Magnetic Phasing for Hands-Free Escape
Magnetic phasing and eddy current braking enable hands-free controlled descent without manual rope operation, improving escape safety.
- Rotary Induction Heater Using DC Excitation to Cut Reactance Loss
A fixed DC coil and rotating pole wheel create an alternating magnetic field for induction heating with far lower reactance loss.
- Magnetic Resistance Control Structure for Exercise Machines
A magnetic resistance unit adjusts overlapping area with a non-magnetically sensitive layer to control flywheel resistance.
