摘要： A thrust reverser control system includes a plurality of actuators, an electric motor, an electric brake, and a control. Each actuator is responsive to an actuator input torque to move between a stowed position and a deployed position. The electric motor is coupled to each of the actuators and is configured, upon being energized from a voltage source having a supply voltage magnitude, to supply the actuator input torque to the actuators and further configured to selectively generate regenerative current. The electric brake is coupled to be selectively supplied with the regenerative current and is configured, upon being supplied with the regenerative current, to supply a braking torque that slows movement of the actuators. The control is coupled to the electric brake and is configured, upon the supply voltage magnitude exceeding a predetermined value, to cause the regenerative current to be supplied to the electric brake.

摘要： An electric motor includes a rotor and a stator. Apart of the rotor includes a first frictional portion forming a movement locus. The stator includes a second frictional portion which brakes and stops the rotation of the rotor by a mechanical frictional force produced by contact between the second frictional portion and the first frictional portion, and a braking actuator which does not allow application of braking by shifting the second frictional portion away from the first frictional portion during power supply to the electric motor, and allows application of braking by pressing the second frictional portion against the first frictional portion during cutoff of power supply to the electric motor.

摘要： A power hoist is disclosed wherein a single operating lever is moved between haul, hold and lock positions. A load may be suspended when the hoist is in hold position by means of braking action which is primarily provided by closing a shunting switch across the leads of a DC motor whereby the motor functions as a brake, which holding action, when necessary, is supplemented by a positive mechanical locking device engageable with the gear train. The combination of electrical shunt holding means with mechanical locking means, both operated by the same lever member enables convenient and improved hoist action in which the load may be securely held in a suspended position without any creepage taking place, and without danger of damage to the mechanical locking system.

摘要： A regenerative braking controller for an AC motor. To determine an electromagnetic torque for slowing or stopping the motor, the regenerative braking controller accesses a lookup table to retrieve an braking torque value corresponding to a current estimate of rotor velocity. The retrieved braking torque may correspond to a maximum or minimum torque level at which regenerative braking will occur at the current rotor velocity, or to a torque level at which charging current during regenerative braking will be maximized. If an external mechanical brake is present, the regenerative braking controller can forward an external braking torque signal to a controller so that the mechanical brake can apply the remainder of the braking force beyond that indicated by the regenerative braking torque. A method for establishing the braking torques to be stored in the lookup table is also disclosed.

摘要： A description of a method and a device for monitoring the braking of a D.C. motor of a printing machine such as a sheet-fed offset printing machine is given. For safety purposes, in the case of an emergency stop an electrical braking should always be carried out with the maximum torque of the D.C. motor. For this purpose, the disclosed method provides that the actual value of the armature current is detected and compared to a maximum permissible value for the electrical braking. In the event of an impermissibly high deviation and, in particular, in the event of an undershoot of the armature current relative to the maximum permissible value, the power converter and motor are disconnected from the power supply and an electrically actuable brake is applied to the motor.

摘要： An automated tape library employing a motorized robotic picker wherein the electric motor driving the robotic picker is equipped with two brakes that act simultaneously. The first is a mechanical brake which uses a spring to push a brake pad against the rotating motor. During normal motor operation, an electric solenoid is used to overcome the spring and disengage the brake pad from the motor. When the robotic picker is to be mechanically stopped, the solenoid voltage is turned off and the solenoid releases the spring placing the brake pad in contact with the motor. The second brake is a dynamic electrical brake which makes use of the back emf of the motor to drive a current back into its own windings such that the motor decelerates.
