摘要： A testing apparatus for minimizing runout of a rotating assembly includes a measurement device and a runout evaluator. The measurement device measures a distance to a surface. The runout evaluator obtains a first runout of a surface of a first member of the rotating assembly from the measurement device. The first runout has a magnitude and a phase. The runout evaluator obtains a second runout of a surface of a second member of the rotating assembly from the measurement device. The second runout has a magnitude and a phase. The runout evaluator determines a rotational position of the first member relative to the second member which results in a reduced runout of the rotating assembly. The determination of the rotational position is based on the magnitude and the phase of the first runout and the magnitude and the phase of the second runout.

摘要： A method of teaching a robot including providing a pin at a location within a work station, and the robot in an area adjacent to the station. The robot having an arm and an end effector that pivots. The end effector has a through-beam sensor including a light emitter and a light receiver to sense when an object is present therebetween. The robot is moved to perform sensing operations in which the sensor senses the pin, such operations are performed while a position and/or an orientation of the end effector are varied to gather sensed position and orientation data. The sensing operations are performed such that the pin is located at different distances between the emitter and the receiver as the robot moves the sensor across the pin. Calculations are performed on the data to determine the location of the pin with respect to a coordinate system of the robot.

摘要： A variable frequency motor drive comprises a converter including a rectifier having an input for connection to an AC power source and converting the AC power to DC power. A DC bus is connected to the rectifier circuit. At least one bus capacitor is across the DC bus. An inverter receives DC power from the DC bus and converts the DC power to AC power to drive a motor. A controller is operatively connected to the converter. The controller comprises a speed control controlling the inverter responsive to a speed command to maintain a desired motor speed. A speed foldback control measures DC bus ripple voltage and regulates the speed command responsive to the measured DC bus ripple voltage.

摘要： A torque coupler includes a first torque plate having a first slot extending in a radial direction, and a second torque plate having a second slot extending in the radial direction. The second slot has a side formed of a flexible beam. A cam plate is pivotable about an axis, and has a cam slot having a first portion at a first radial distance from the axis and a second portion at a second radial distance, where the second distance is greater than the first distance. A torque transfer member is slidably received within the first slot, the second slot, and the cam slot. The transfer member transferring torque between the first and second torque plates. A drive device rotates the cam plate about the axis, which causes the first cam slot to radially slide the transfer member along the flexible beam.

摘要： A Variable Frequency Drive (VFD) supplies power to rotate a motor, controlling both the speed and direction. The method normally used for this power conversion by the VFD results in energy losses and line harmonics. When the motor is driven by the VFD to be rotating at the same speed and direction as if the motor was straight across the incoming AC power, a transfer in power supply to the motor can be made using contactors to bypass the VFD. When in this bypass mode, the energy losses of the VFD are greatly reduced, and the line harmonics due to the VFD are greatly reduced. When it is subsequently recognized that the speed reference has deviated from being the same speed and direction as if the motor was straight across the incoming AC power, a transfer in power supply can be made from using contactors to once again drive the motor from the VFD.
摘要翻译：变频驱动（VFD）提供电源旋转电机，同时控制速度和方向。通常用于VFD进行功率转换的方法会导致能量损耗和线路谐波。当电动机由VFD驱动以与电动机直接进入交流电源相同的速度和方向旋转时，可以使用接触器对电动机进行电力转换以绕过VFD。在这种旁路模式下，VFD的能量损耗大大降低，VFD引起的线路谐波大大降低。当随后认识到速度基准已经偏离与输入的交流电源直线相同的速度和方向时，可以使用接触器进行电力供应，从而再次从VFD驱动电动机。
