A Primer on Generator Functionality

Electrical generators convert mechanical energy into electrical energy through electromagnetic induction. Inside every generator is a rotating component known as the rotor and a stationary component called the stator. A prime mover—often a diesel or natural gas engine—turns the rotor. As it spins, a magnetic field cuts across stationary windings in the stator, inducing an electrical current. Voltage regulators, cooling systems, and fuel delivery mechanisms all coordinate to deliver steady, usable power.

• Rotor and stator interaction creates a consistent electrical output
• Voltage regulation ensures appliances receive stable current
• Cooling systems prevent overheating under load
• Automated control panels engage the generator within seconds of a power loss
