Crane hoists, conveyors etc. A compound DC motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series DC motor. The function of commutator in the motor is the same as in a generator. Since these motors are considered constant speed, there is usually a base speed provided on the spec. Product Specs Input Voltage: 12-115 volts RPM: 1,000-7,500 RPM Torque: XXX IN-LBS Horsepower: 0.025-1.0 HP Of these, the yoke, the pole cores, armature core and air gap between the poles and the armature core form the magnetic circuit whereas the rest form the electrical circuit. The above write-up only describes some of the prominent brushed dc motors. Riedon DC Ammeter Shunts are specified by series Type, watts and resistance. N / T characteristic, also known as mechanical characteristic. The other three types are classified based on the electrical connections between the stator and the rotor. Common uses of the shunt motor are machine shop lathes, and industry process lines where speed and tension control are critical. So, characteristics become a straight line. The characteristic curves of a motor are those characteristics which show relationship between the following quantities: a)Torque and armature current i.e. These motors are available in a variety of sizes. Contact DC Motors Inc. for more information and for recommendations on the suitability of various wound-field DC Motors for your applications. Hence speed is low (this decreases Eb and allows more armature current to flow).
