Harting's Han-Drive range of motor connectors are the key element in a new plug-in motor connectivity concept developed by motor manufacturer Brook Crompton.

Brook Crompton's plug-in motor concept for ease and economy of installation Harting's Han-Drive range of motor connectors are the key element in a new plug-in motor connectivity concept developed by motor manufacturer Brook Crompton Collaboration between Harting and Brook Crompton has resulted in a range of motors which can be easily and quickly installed, replaced and maintained without the need for specialist electricians or mechanical fitters

Not only is Brook Crompton supplying motors complete with the Harting connectors ready-mounted: the company is also marketing kits of parts to allow users to retro-fit the connectors to earlier motors.

The plug-in approach eliminates the need for a motor terminal box and board that typically incorporate at least six terminals for all the supply cables and any auxiliaries in an indiustrial motor installation.

Resultant benefits include not only the ease and speed of installation, minimising expensive labour costs, but also the elimination of the possibility of human error causing misrouted connections.

The latter point is particularly significant where motor/drive installations are broken down prior to shipping overseas and being reassembled - often in parts of the world where there is a shortage of skilled engineers.

Further impetus towards the use of plug-in motors has been created by the UK Government's forthcoming Climate Change Levy, which will offer capital-allowance incentives to companies who replace older motors with modern, more energy-efficient types.

The costs to companies contemplating wholesale motor changes in the interests of energy efficiency will be significantly reduced by the plug-in approach.

In the system developed by Brook Crompton and Harting, motor connection is via a male housing (plug) attached to the motor frame, which is connected to its mains supply via a matching hood (female socket).

Inserts can be provided with up to ten pins and a maximum output of 11 kW, and all devices meet key national and international standards including VDE, DIN, CECC, UL and CSA.

The connectors are also compatible with the DESINA standard, which originated within the German machine-tool industry and is rapidly becoming adopted in a wide variety of decentralised industrial motor and control applications.
