A control system is configured such that a carriage that a processing head is mounted is driven by a motor and reciprocates. The motor is controlled by a controller. The controller reciprocates the carriage by selecting a control mode as a target mode based on temperature information related to temperature of the motor and controlling the motor in the target mode. The controller selects the target mode to be applied to the control of the motor for each of particular work units. The target mode is selected from a group of particular control modes. Each control mode in the group of particular control modes is a control mode in which a maximum temperature, which is estimated based on the temperature information, when the control of the motor using the selected control mode would be executed until the processing is completed, is less than a reference value.

An integrated multimode thermal energy transfer system, method and apparatus for full-scale clean fuel electric-powered multirotor aircraft with automatic on-board-capability to provide sensor-based temperature awareness and adjustment to critical components and zones of the aircraft. Automatic computer monitoring, including by a programmed triple-redundant digital autopilot computer, controls each motor-controller and motor to produce pitch, bank, yaw and elevation, while simultaneously measuring, calculating, and adjusting temperature and heat transfer of aircraft components and zones, to protect critical components from exceeding operating parameters and to provide a safe, comfortable environment for occupants during flight. By using the results of the measurements to inform computer monitoring, the methods and systems can use byproducts including thermal energy disparities and differentials related to both fuel supply systems and power generating systems to both add and remove heat from different aircraft zones to improve aircraft function, comfort, and efficiency.

A terminal assembly for a traction motor includes a bus bar having a ring shape and a terminal holder configured to accommodate the bus bar therein to cover an exterior of the bus bar. The terminal assembly includes: the terminal holder which is perforated to form a coupling hole therein through which a surface of the bus bar is exposed; and a temperature sensor unit which is inserted into the coupling hole and senses a temperature of the bus bar.
