6. Review problem: A cradled DC motor dynamometer is used to test the output of a...
A permanent magnet DC motor is supplied from a 12 V source and turns at 500 RPM (steady-state) experimentally determined as 0.1 Nms2 and the frictions are negligible. The electrical parameters of the rotor winding are measured 0.82, and 5mH. Obtain the transfer function of the motor by considering the armature voltage as input and shaft speed in rad/s as output. with an armature current of 1A. The moment of inertia is

INTRODUCTION
With the increase in recreational and competitive cycling,
cyclists are experiencing more overuse inju- ries related to
repetitive loading.Both intrinsic and extrinsic factors contribute
to injury. Intrinsic fac- tors are inherent to the cyclist and
include fitness level as well as anatomical alignment of the lower
extremities. Extrinsic factors are generally asso- ciated with
factors external to the...
