Abstract: A system and method for slowing the rotation of a rotor using, for example, rotor brake system for a rotorcraft comprises: one or more generators connected to a main rotor gearbox; an electric distributed anti-torque system mounted on a tail boom of the rotorcraft comprising two or more electric motors connected to the one or more generators, wherein the two or more electric motors are connected to one or more blades; and wherein a rotation of the rotor is slowed by placing a drive load on the main rotor gearbox with the one or more generators to bleed the mechanical power from rotor into electrical power via the two or more electric motors, wherein the electric distributed anti-torque system generates thrust in opposing directions.

Abstract: The disclosure describes an automated aerial vehicle (AAV) and system for automatically detecting a contact or an imminent contact between a propeller of the AAV and an object (e.g., human, pet, or other animal). When a contact or an imminent contact is detected, a safety profile may be executed to reduce or avoid any potential harm to the object and/or the AAV. For example, if a contact with a propeller of the AAV by an object is detected, the rotation of the propeller may be stopped to avoid harming the object. Likewise, an object detection component may be used to detect an object that is nearing a propeller, stop the rotation of the propeller, and/or navigate the AAV away from the detected object.

Abstract: A system for braking an electric motor. For each motor winding, a first switch is connected between the winding and electrical ground and in series with a resistor and is closeable to connect the winding to ground through the resistor, and a second switch is connected between the winding and ground and is closeable to bypass the resistor. A controller receives feedback regarding the speed and sends to the second switch a pulse width modulated signal which selectively opens and closes the second switch to connect and disconnect the resistor to achieve an optimal equivalent average stator resistance for the motor speed which results in a power transfer to the resistor and increases a braking torque as the motor slows. The pulse width modulated signal opens the second switch for a longer time when the motor speed is higher and for a shorter time when the motor speed is lower.

Abstract: The embodiments herein provide a self-excited contact less Hybrid Electromagnetic Braking (HEB) system provided with a both Permanent Magnetic (PM) type ECB and electrically excited windings type ECB. The HEB system has an Eddy Current Brake (ECB) and a Regenerative Brake (RB) with two outer rotors and a common internal stator. The rotor assembly of the RB is coupled to the same shaft on which the ECB rotor is mounted. The RB collects an input mechanical power from the shaft to supply electrical power to ECB windings through a power electronic interface module. A controller measures the system conditions to send a control signal to the power electronic interface module to control a power flow from RB to ECB. The ECB and RB develops two braking torques on the shaft to initiate a braking action in the vehicle.

Abstract: A method for maximizing regenerative energy captured by an electric machine in a powertrain including an engine, the electric machine and a transmission device configured to transfer torque through a driveline includes detecting an operator brake request and monitoring a time between the detected operator brake request and a preceding operator brake request that was last detected. A maximized regenerative deceleration event is initiated if the time exceeds a predetermined threshold time that includes monitoring a current fixed gear ratio that is selected from among a plurality of fixed gear ratios of the transmission device when the operator brake request is detected and applying a magnitude of torque at the axle that is sufficient for achieving a maximum capability of the electric machine to capture regenerative energy in the current fixed gear ratio.
