Implementation of the Closed-Loop Transmitter

Abstract

With a complete analysis of design optimization parameters complete, this chapter turns to the design and manufacturing of the mechanical system. The fundamental design constraint on the system is the torque requirement $\tau _{req}$ of the rotating assembly. Findings from Chap. 6 establish guidelines regarding the trade-off between modulation rate $\alpha _{max}$ and field generation $m_{dip}$. The mechanical component of the AMEBA2 transmitter is introduced in this chapter. A motor driver (power amplifier) is designed and tested in Sect. 7.2 in order to build appropriate background information for assembly testing. Note the driver will remain abstract from the control system until the latter subject is introduced in Chap. 8. The remainder of the chapter covers the machining and assembly of the unit cell. In Sect. 7.1, we specify hardware components and design the unit cell.
