A Numerical Method of the Electromagnetic Force for the Electromagnetic Track Brake
Applied Mechanics and Materials, 2012The object is to propose an accurate and succinct numerical method to compute the electromagnetic force between the electromagnetic track brake and track. The model of the magnetic circuit with variable air-gap permeance is established and the electromagnetic force is obtained by using a method of magnetic flux tubes.

Magnetorheological suspension electromagnetic brake
Journal of Magnetism and Magnetic Materials, 2004Abstract The magnetorheological suspension (MRS) brake is of the monoblock type. The main part of the electromagnetic brake is an electromagnet, between whose poles two MRS disks are placed. For distances between disks of 0.65×10−3 m±10%, revolutions of the electric motor, coupled to the electromagnetic brake, ranging between 200 and 1600 rev/min and

Electromagnetic braking for Mars spacecraft
22nd Joint Propulsion Conference, 1986Aerobraking concepts are being studied to improve performance and cost effectiveness of propulsion systems for Mars landers and Mars interplanetary spacecraft. Access to megawatt power levels (nuclear power coupled to high-storage inductive or capacitive devices) on a manned Mars interplanetary spacecraft may make feasible electromagnetic braking and ...

Electromagnetic brake with controllable torque
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1961MANY LARGE materials handling machines and processing machines require smooth, accurate stopping. In the past, accurate stopping has usually been accomplished by the use of hydraulic brakes. Recently, an electromagnetic brake has been developed to perform the same functions and to overcome some disadvantages of hydraulic brakes, such as the need for ...

Electromagnetic braking of a metallic projectile in flight
IEEE Transactions on Magnetics, 1985A simple model for the electromagnetic deceleration of a moving metallic projectile is described. It incorporates the influence of magnetic field parameters, time-dependent field diffusion, and device geometry on braking action, albeit in an approximate fashion. The model predicts that a viable experimental braking device can be designed.

Diagnostics of Electromagnetic Friction Brakes and Clutches
2019 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2019This paper proposes and theorizes upon a new method for diagnosing movable-armature electromagnetic mechanisms (EM), which is based on an additional high-frequency electric-field effect on the EM magnetic core; the field excites corresponding high-frequency electrodynamic processes that are not related to the EM operating parameters and do not affect ...

Design and Analysis of a Regenerative Electromagnetic Brake
IEEE Transactions on Magnetics, 2014In this paper, a regenerative electromagnetic brake, which has the same structure as conventional electromagnetic brakes and the same principle as self-excited induction generators, is introduced, and a miniature model is designed. The most important part of the design stage is to choose proper equivalent circuit parameters for self-excitation within a
