The Commercial Electric Co.'s Iron Clad Motor — We illustrate herewith the new ironclad motor which has recently been brought out by the Commercial Electric Co., Indianapolis, Ind. They are built for two standard speeds and are intended for a variety of uses. In Figs, 1, 2 and 3 they are shown mounted on the ceiling. The magnet frame is of steel with circular cores and pole shoes of the same material, thus affording a low resistance air gap and the greatest possible efficiency of the magnetic circuit, while the end casings which carry the bearings are of cast-iron and are provided with ample, ventilating holes. The workmanship and material throughout are of the highest class. The shafts are of steel and bearings self-oiling with bronze linings, which are easily renewed. Carbon brush holders of simple construction and large capacity are used, and owing to the strong magnetic field sparking and change of lead are avoided, so that the machines may run for a long time and require little attention. They arc thoroughly protected from mechanical injury, dust and dirt, while the large lids which are placed in the casing above and below the commutator allow of easy access to the brushes when desired. When suspended as shown in the cut, the operation of the belt tightening device is in no way interfered with or more inconvenient than when mounted on the floor, since there are no bolts to be loosened, but the machine can be mounted on its own support as with other ceiling machines. It is extremely convenient for direct belting to elevator machines when used in this way and the company makes a special reversible motor and controller for this purpose. The machine, it is needless to add, runs equally well if placed on the floor or regular foundation. The company will be glad to answer any inquiries on the subject. |
