Abstract
An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. Logistics electronics are mounted proximate a first end of the drum and power electronics are mounted proximate a second end of the drum. In general, the logistics electronics include lower power electronics that enable data processing as well as data and commands to be communicated to the apparatus from an external location. By contrast, the power electronics may include higher power electronics needed to receive power and drive the motor.
