Claim 0:
1. An integrated motor and motor drive arrangement comprising:
a motor having:
a stator; and
a rotor, rotatable relative to the stator to drive a load, the rotor being arranged radially outside the stator, and the stator having an inner surface defining a radially inner space, the inner surface machined to define a plurality of interior flat panels;

the motor arrangement further comprising:
motor drive components mounted to the interior flat panels of the inner surface of the stator within the radially inner space, the motor drive components including:
power converter components arranged in one or more power converter modules each mounted to a respective interior flat panel of the inner surface of the stator;
one or more DC link capacitors each mounted to a respective one of interior flat panels adjacent a flat panel on which a power converter module is mounted, the one or more DC link capacitors connected to respective power converter modules by DC link bus bars and a gate drive for each of the one or more power converter modules, each gate drive assembled over but radially spaced from the respective DC link bus bar.
