A simple DC motor has a coil of wire that can rotate in a magnetic field. The current in the coil is supplied via two brushes that make moving contact with a. An engine-generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of self-contained. Motor generators are used to isolate electrical loads from power supply lines. It consists of an electrical generator driven by an electric motor. Rule #1: For generation of DC voltage select a brushed DC motor or use a brushless EC (BLDC) motor with voltage rectifier. For the generation of AC voltage, select a brushless EC motor and connect 2 phases only. Hall sensors are not needed on brushless motors. Speed constant kn. Many generators are operated at speeds of rpm or below. Calnetix electric generators and high speed motors: Magnaforce Permanent Magnet (PM) Motor Electric Generators are for a variety of applications and industries. These units range from only a few watts to megawatt power levels with high speeds ranging from 4, rpm to , rpm (high speed motor).
