Electric motor speed control apparatus and method

Abstract: The speed of an induction motor is reduced by initially using dynamic electrical braking to slow the motor to a speed at which it will not remain synchronized to the A.C. supply frequency. At this point, A.C. cycle skipping is employed to apply current to the motor at an effective frequency which is a fundamental frequency component of the A.C. supply line frequency. The motor becomes synchronized to this fundamental frequency component. If desired, the motor can be brought to a complete stop by discontinuing the cycle skipping and using the dynamic braking again for a given period of time. This technique provides a very controlled stopping of the motor enabling equipment driven by the motor to be accurately positioned.

On the Braking Behavior of Motorcycles

Abstract: This work presents a study on the braking style and its implications on motorcycle stability. First, a simplified motorcycle model is used for highlighting basic phenomena which occur during braking and for developing an ideal braking strategy. Then, braking maneuvers are analyzed using a detailed multi-body model, which takes into account all relevant characteristics of a motorcycle, such as geometry, mass and inertia distribution, non-linear suspension and tire properties. Simulations are repeated for dry and wet road conditions, showing that the correct braking style should change as the adherence conditions change, according to the suggestions given by the simplified model. Finally, stability analysis is carried out for different speeds, deceleration rates and braking styles, showing that a correct braking balance may significantly improves vehicle stability.

Self-sourcing exercise bike with a linear digital control magnetic resistance braking apparatus

Abstract: A self-sourcing exercise bike with a linear digital control magnetic resistance braking apparatus comprises a generator, a power converter, a digital control system, a magnetic braking resistance and a LED control panel. This apparatus uses a linear control method to control the change of the magnetic resistance, and the magnetic resistance braking apparatus uses a method of changing inductance and a controlling way thereof to achieve the goal of controlling the variation of the magnetic resistance braking force. This bike makes the user or rehabilitant to linearly adjust the resistance force or torque according to the speed of the exercise bike and the presetting resistance force, and easily start up the power system in the initial stage.

Vehicle braking system and method of braking

Abstract: A vehicle braking system having one brake circuit actuated directly by pressure generated in a master cylinder and a second brake circuit actuated, by pressure generated by actuation of the master cylinder, to the extent that regenerative braking effort acting on the wheels having brakes in the second brake circuit is insufficient to provide the desired total braking effort on those wheels. When regenerative braking on those wheels is sufficient to meet the braking effort demand, the service brake system does not supply any additional braking effort. A compliance control member provides the feel of input travel and force equivalent to the regenerative braking effort actually at the wheels of the second brake circuit when regenerative braking is occuring while the vehicle is being braked. The absorbed displacement and force is fed back to the second brake circuit by the compliance control member when the regenerative braking effort becomes insufficient to meet the braking effort demanded from the brakes of the second brake circuit.

Braking torque control using recurrent neural networks

Abstract: The basic problem in the operation of automotive brakes is the unpredictable nature of the tribological processes that occur at the contact of the friction pair. The stochastic nature of the tribol...
