Abstract: A plurality of fan blades are secured to a rotor assembly of a single directional motor. When the motor is powered on, a force generated by the fan blades pushes the rotor assembly in a direction of a low friction thrust interface. When the motor is backdriven in a direction opposite the powered direction, the force generated by the fan blades pushes the rotor assembly in a direction of a higher-friction thrust interface, causing a tapered surface of the pinion and a tapered surface of a bearing retainer to be pressed against each other to produce a frictional braking force. The backdriven speed of the motor and drive device is therefore reduced, improving the reliability of the motor assembly. The invention can be applied to motor actuators used to control air dampers and other valves in gas or fluid delivery systems. The invention can also be used to reduce water hammer in water delivery systems.

After performing the dynamic impedance matching in this braking system, the EMABS effect and recycling of the regenerating energy on braking are accordingly obtained.

Abstract: A motor brake can be coupled to the rotatable motor drive shaft. The brake includes a shaft-mountable support that rotates uniformly with the drive shaft. One or more brake shoes, which can include flyweights or the like, are hingedly mounted to the support and include brake pads. A centripetal force is applied to the brake shoes using one or more springs or other biasing means that bias the brake pads against a braking surface when rotation of the shaft is below a minimum rotational velocity.

The centrifugal force induced and applied to the brake shoes and brake pads by rotation of the motor drive shaft overcomes the biasing force to disengage the brake pads from the braking surface, which may be the housing of a motor to which the brake is affixed.

Abstract: A braking force is generated by using a rotation of an electric motor to move a piston, which presses friction members onto a rotor. The displacement of the piston is controlled such that a detection value of a resolver becomes a target value. In the case of brake noise due to vibration of the rotor, the displacement of the friction members with respect to the rotor fluctuates in connection with the rotation of the rotor, leading to fluctuations in a rotational amount of the electric motor. Therefore, in a simple method and apparatus, brake noise can be detected based upon the magnitude of the fluctuation amount in the detection value of the resolver.
