Field coil for P&H RT-175

The field coil 6481Z48 is an electrical component used within direct current motors and generators found in heavy machinery. It consists of a conductive wire winding wrapped around a ferromagnetic core, which serves to create the stationary magnetic field required for the motor to produce torque or for a generator to induce voltage. This interaction between the field coil and the armature windings is the fundamental principle that allows these electrical machines to convert energy effectively.

This specific component is engineered for the P&H RT-175 rough-terrain crane. It is integrated into the electrical systems that support various crane functions, such as the turret swing system, hoist drum motors, or auxiliary power generation units. By maintaining the integrity of the magnetic field, this coil ensures that the motor operates within its intended parameters for power and control during lifting and maneuvering tasks.

In any electrical motor or generator, the field coil is responsible for establishing the magnetic flux that interacts with the rotating armature. Proper function of this coil is necessary for the motor to reach its rated output and maintain stable operation under load. When integrated into the crane's electrical architecture, it supports the consistent performance of the machine's drive and hoist systems.
