  • Publication number: 20190319570
    Abstract: A brushless DC motor system includes a brushless DC motor having phases and a controller in communication with the motor for operating the motor in accordance with a commutation table. The controller further has nodes. The system further includes phase wires electrically coupling the motor and the controller at the nodes to form wire-to-node connections for establishing electrical communication paths between the motor and controller along each phase wire. Each phase wire corresponds to one phase of the motor. The controller is programmed to, in response to a user-selected configuration of the wire-to-node connections, generate the commutation table.

  • Publication number: 20180177652
    Abstract: A patient transfer apparatus is provided and includes a frame, a seat assembly coupled to the frame, and a track assembly coupled to the frame. The track assembly includes a moveable track for traversing stairs and a motor configured to drive the track. The apparatus further includes a control system. The control system includes a controller configured to control the motor and to adjust a speed of the apparatus based on at least one of an occupancy of the seat assembly upon traversing the stairs and a condition of the stairs.

  • Publication number: 20170281440
    Abstract: A patient support apparatus includes a frame, wheels, a patient support surface, a motor, a power assist control, a sensor, and a controller. The power assist control detects a force applied to it. The sensor detects an angular orientation of the patient support apparatus with respect to a generally horizontal plane. The controller drives the motor at different levels for a particular force applied to the power assist control depending upon the angular orientation sensed by the sensor. The controller may control the motors such that the patient support apparatus accelerates at substantially the same rate, regardless of the angle of the patient support apparatus. The controller may also limit the driving of the motor to less than a maximum value based upon the angular orientation of the patient support apparatus.
