318372000 | Friction braking | 7 |
20110169433 | SERVOMOTOR SYSTEM WITH INTEGRATED BRAKE CONTROL - A servomotor system is provided. The servomotor system includes an enclosure and a motor stator and rotor disposed in the enclosure. The servomotor system also includes a motor brake disposed in the enclosure and configured to selectively brake the rotor from rotation and a brake control switch disposed in the enclosure and coupled to the motor brake for selectively providing power to the motor brake for selectively engaging and/or disengaging the brake. | 07-14-2011 |
20120139457 | ELECTRONIC DRIVE HAVING AN ELECTRO-MECHANICAL BREAK - An electronic drive includes an electro-mechanical brake associated with a direct-current motor. A first valve or diode connects one of the terminals of the direct-current motor with the first electrical terminal of the brake in a forward direction. A second valve or diode connects the other terminal of the direct-current motor with the first electrical terminal of the brake. A second electrical terminal of the brake is at least indirectly connected with a reference voltage. | 06-07-2012 |
20130141022 | SIMPLIFIED ELECTRIC BRAKE DEVICE - An electric brake device is provided for electronically controlled synchronous motors which are supplied with voltage by way of a converter. The synchronous motor contains a winding center point and that the winding center point is connected by way of an electric resistor and a switch to a ground point of the converter and that the phases of the converter that are connected to the ground point contain in each case a free-wheeling diode. | 06-06-2013 |
20130154522 | Method and Apparatus for Calibrating and Testing Brake Holding Torque - A system and method for determining the holding torque of a brake in a material handling system is disclosed. The material handling system may include a bridge, a trolley, and a hoist, each driven along a different axis by a motor. A brake is operatively coupled to the motor to prevent unwanted motion of the motor. A motor controller is coupled to each motor which controls operation of the motor and its corresponding brake. The motor controller generates a torque command to the motor while keeping the brake set. The initial torque command is less than the holding torque of the brake. The torque command is incremented until motion is detected on the motor. The torque value when motion is detected is stored in the motor controller and displayed to an operator. | 06-20-2013 |
20140232303 | DRIVE UNIT AND METHOD FOR OPERATING THE DRIVE UNIT - A drive unit for operating a device, in particular a device in a vehicle and a method for operating a drive unit are provided. An electrical drive assembly and a break assembly are combined and arranged together in a common housing. The breaking assembly could be a mechanical breaking assembly or an electrical break assembly. The break assembly automatically locks the shaft of the electrical drive assembly and thus provides self-locking capabilities. | 08-21-2014 |
20150340973 | BRAKE CONTROLLER - A system and method for controlling a brake coil in a motor having a control processor and a controller in communication with the control processor, the controller comprising a processor and memory with instructions stored thereon when executed by the processor cause the controller to receive signals indicative of threshold current values for the brake coil; provide enabling signals to each of a high-side and low-side driver circuit; receive signals indicative of a sensed current in the brake coil; compare the sensed current with the threshold current values; and provide an adjustment signal if the sensed current is outside a known range of values for the threshold current values. | 11-26-2015 |
