Honda Power Equipment TPG-6000H-DX, TPG-2900H-DX Tsurumi’s Operation, Service, and Repair Manual

Tsurumi’s Operation, Service, and Repair Manual

(b)The generator consists of a tubular frame onto which is installed the generator, engine, front panel, control box and fuel tank.

(c)The generator and engine are installed on crossover plates that form the base of the tubular frame. Vibration isolators support the generator and engine unit. The isolators are fitted with threaded studs that secure the generator and engine unit to the frame.

(2)Description of Generator

(a)The generator consists of a rear cover, stator cover, stator, rotor, and front cover.

(b)The front cover of the generator attaches to the engine and forms the generator-to- engine interface.

(c)The front cover has a series of slots that allow entry of cooling air into the generator. A fan on the rotor circulates air through the generator.

(d)The rear cover has mounting lugs that are the generator-to-frame attachment points. The rear cover supports a ball bearing at the back end of the generator rotor.

(e)The rear cover has a removable access plate to provide access to the stator wiring (an access plate is not used on Model TPG-2900H-DX.)

(f)The rotor consists of a shaft, a stack of steel laminations, and copper wire windings. Components mounted on the rotor include a diode, a surge absorber, two permanent magnets, and a cooling air fan.

(g)The windings and the laminated steel core form the field coil. The permanent mag- nets are used to induce voltage in the main coil of the stator. The diode and the surge absorber are located under the rotor windings at the bearing end of the rotor shaft.

(h)The rotor is attached to the engine crankshaft with a through bolt (tie-bolt). The engine crankshaft is tapered and mates with a tapered bore in the rotor shaft. The clamping force applied to the through bolt ties the rotor shaft to the engine crankshaft.
