The Company's Products

This section contains details of some of the many and varied products that were produced by the company, in the 1930's and 1940's. At this time the principal products were rotating electrical machinery, switch and control gear, static transformers, and rectifiers.

An advert from 1920 showing an E.C.C. motor driving a steel rolling mill.

One of E.C.C.'s larger DC motors. It was installed at a rolling mill and operated in conjunction with a steam-turbine driven generator. The motor was rated at 5,000b.h.p., at 55r.p.m. It was reversible and could reverse direction from full speed in one direction, to full speed in the opposite direction, in seven seconds. The speed could be adjusted by varying the current in the field windings. The maximum speed was 110r.p.m.

Two synchronous three phase 600b.h.p. motors, that were used to drive air compressors in a colliery. The motors also provided power factor control, so that the equipment operated at its greatest efficiency.

Part of a large installation at a spinning mill. The squirrel cage motors were capable of delivering 10b.h.p., and were driving ring-spinning frames.

The company produced switchgear to control all types of AC and DC motors and generators. Some of the switchgear, called "trucks" was mounted on wheels to allow easy access. The photograph shows part of 60 high tension "trucks" that were installed in a metropolitan borough power station, to control the outgoing supplies.

The E.C.C. built all types of transformers, up to 10,000K.V.A. The photograph shows a 10,000K.V.A. unit of the outdoor type, with a conservator and oil-cooling radiators.

A 2,200 volts, 65K.W., rectifier unit, using two mercury arc rectifiers, oil-cooled transformer and D.C. switchgear. It was built for a Corporation electricity department and delivered an output of 220volts D.C. at 65K.W.

A small metal-plate rectifier unit that was built for a Government department and used to supply a wireless telegraph communications system.

The equipment opposite was installed in a steel works. It consisted of a 500b.h.p. motor, with a speed range of 150 to 350r.p.m., a 750K.W. rectifier unit, which provided 480 volts D.C., from a three phase A.C. input, of 5,500 volts. There was also a second motor that was rated at 350b.h.p. The control switchgear is on the right.

An E.C.C. patent varispeed drive, applied to a machine tool. It consisted of a mercury arc rectifier, variable speed D.C. motor, and the necessary control gear.
