A century of submersible motors

A Hayward Tyler product story
Edited by the Engineeringtalk editorial team Aug 28, 2008

The 100th anniversary of the first submersible electric motor coincides with the successful testing earlier this year of the first of three of the largest ever subsea motors built by Hayward Tyler.

Hayward Tyler is celebrating 100 years since designing the first submersible electric motor.

In 1908, the company patented the first unit of this type, which was designed for marine salvage operations.

The early design consisted of a squirrel-cage motor with rubber-insulated stator windings.

The pump was a single-stage unit, having a medium output against a comparatively low head.

The pump had a 6in discharge branch and was capable of an output of 200 tonnes of seawater per hour against a head of 23m.

The motor was rated at 15kW and operated on 220V, three-phase, 50Hz at 1460rev/min.

The celebration coincides with the successful testing earlier this year of the first of three of the largest ever subsea motors built by Hayward Tyler for its customer Aker Solutions.

The qualified Hayward Tyler design for the 2500kW variable speed, super synchronous motor, will operate at speeds ranging from 2500 to 4000rev/min.

Mark Wood, Group Sales and Marketing Director at Hayward Tyler commented: "2008 is a milestone celebration for Hayward Tyler".

"The company already has an enviable heritage, being almost 200 years old".

"To consolidate and grow the business for this length of time and still remain leaders in submersible motor technology, is an outstanding achievement".

"We look forward to further developing our product technology to even larger sises in order to meet the challenging operating conditions of the subsea market".

To celebrate this news, the company is giving away free prizes via its website, including an iPod touch and a Nintendo Wii games console.
