A: The grinder pump will be owned by the drainage district, as is the pressure pipe on private property. The drainage district maintains the grinder pumps.
A motor which can be operated either on DC (direct current) or on single phase AC (alternating current) is called a universal motor. On both AC and DC, it gives approximately the same speed and output. Universal motors often run at dangerously high speed when operated at no load. This means that motor speed will be low at full load, but the speed of the motor will start increasing as the load on the motor decreases.
Construction of DC Motor | Yoke Poles Armature Field Winding Commutator Brushes of DC Motor. A DC motor like we all know is a device that deals in the conversion of electrical energy to mechanical energy and this is essentially brought about by two major parts required for the construction of DC motor, namely. 1  Stator â The static part that houses the field windings and receives the supply and,
