4.2 System Configuration and Documentation

The application is designed to drive the 3-phase BLDC motor. The HW is a modular system composed from board and motor. There are three possible hardware options:

•High-Voltage Hardware Set Configuration

•Low-Voltage Evaluation Motor Hardware Set Configuration

•Low-Voltage Hardware Set Configuration

The following subsection shows the system configurations.

They systems consists of the following modules (see also Figure 4-1,

Figure 4-2,Figure 4-3):

For all hardware options:

•MC68HC908MR32 Control Board

For High-Voltage Hardware Set cofiguration:
