   Powerpack removal of an M75 APC. A powerpack or power pack is a part of a modular powertrain that contains some type of engine (most frequently an internal combustion engine, ⁣⁣ but other types, including electric motors, are possible) and may also contain a transmission and various supporting components.

   Hydraulic power pack; Transmission lines Hydraulic hoses; Passive components Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types.

   Hydraulic pressure was provided by three hydraulic pumps fitted to Nos. 1, 2 and 3 engines. An electrically operated hydraulic power pack (EHPP) could be used to operate the bomb doors and recharge the brake accumulators. A compressed air (later nitrogen) system was provided for emergency undercarriage lowering. [119]

6. Traction motor - Wikipedia

   en.wikipedia.org/wiki/Traction_motor

   AC induction motors and synchronous motors are simple and low maintenance, but up until the advent of power semiconductors, were awkward to apply for traction motors because of their fixed speed characteristic. An AC induction motor generates useful amounts of power only over a narrow speed range determined by its construction and the frequency ...

   The DC system is powered from two 28 Volt, 400 Amperes, engine-driven starter-generators. Two 24 Volt batteries provide standby power for the DC system and are used for engine starting. AC current is provided by two 1000 Volt-Amperes (VA) solid-state inverters. The inverter outputs are frequency synchronized through a paralleling bus tie.
