Axial Airgap Motors
The axial airgap motor concept is different from a conventional
totally enclosed motor in that it has a very short length but is
larger in diameter. It is an ideal solution for equipment manufacturers
(OEM's) requiring compact motors in large batches. It is available
in outputs from 100W up to 2.2kW in frame sizes AAG115, AAG145 and
AAG181. The construction is equally suited to single phase, multi-speed
or induction generator designs aswell as the standard 3 phase design.
The principal advantage of the axial airgap motor lies in its configuration
where the overall length provides OEM's with competitive advantages
for their own products, for example fans where the overall depth
of the fan can be significantly reduced. Other applications include
floor polishers, hoists, pumps and compressors. Application requirements
such as torque, noise or optimisation of efficiencies can be accommodated.
The optimisation of the motor design and the exploitation of opportunities
for integration, such as shared bearing arrangements and customised
enclosures, benefits from involvement early in the equipment product
development cycle and joint development programmes.

Drip Proof Motors
The Drip proof motor range has been designed to optimise the customer
benefits of a high power to weight ratio and covers products with
outputs from 30kW to 265kW in frame sizes K-CF225M to K-CF315M,
in either 2,4,6 or 8 pole speeds.
The Drip proof range of motors are an ideal option where weight,
size or cost per kW output are important. They are suitable for
relatively clean environments and locations where a degree of protection
is already afforded to the motor, eg. pump houses. Typical applications
are compressors, fire pumps and marine duties, etc.
All motors have an IP23 enclosure as standard. This means that
motors are protected against the harmful ingress of solid and foreign
objects and against the harmful ingress of water (spray) falling
at 60 deg to the vertical shaft mounting.
The Drip proof range utilises cast iron integral foot frames, endshields
and terminal boxes, with asteel fan cover. All drive endshields
are pre-machined to take a flange adaptor without further modification.
Features include:
• IP23 enclosure
• Top mounted terminal box - RHS and LHS options available
• Compressor speed torque curve

Permanent Magnet Motors
The MP range covers outputs from 0.25kW to 1.5kW, IP22, IP44 or
IP55 IC01/IC410. The permanent magnet motor can be used in variable
sped drive applications as a replacement for the separately-excited
shunt motor with the advantage that there is no need for a field
supply, and the field excitation wiring between controller and motor
and motor is eliminated. Permanent magnet motors have a smaller
diameter body than the equivalent wound field motor. However, permanent
magnet motors do not have the facility of field trimming

Marine Motors
Marine duty motors are designed and rated for use on board merchant
ships built anywhere in the world and in accordance with the requirements
of the major marine clsssification authorities. These requirements
generally concern limits to winding temperature rises with given
ambient temperatures, which determine the motor frame size for a
given output. For certain larger motors some authorities specify
normalised shaft steel to give greater consistency. The requirements
for witnessed tests, type tests, certification etc. differ between
authorities and all can be accommodated. However these exceptional
demands must be made clear at the time of ordering.
Brook Crompton Marine motors can be offered in either aluminium
or cast iron material, the choice be determined by factors such
as weight, appearance, efficiency, applications etc. The paint finish
and winding protection are chosen to suit the harsh marine environments
in which the motors have to perform.

Monsoon Motors
Monsoon tropical treatment was developed by Brook Crompton to protect
motors from corrosion when operating in hostile environments including
tropical climates and industries such as petrochemical, paper, glass-making
and textiles where they are subjected to frequent deluge and heat/thermal
cycling. These conditions cause condensation to form on the internal
surfaces of the motor and the resulting corrosion can cause irreparable
damage to stator windings and moving parts on unprotected motors.
A large number of Brook Crompton Monsoon Tropical Treatment motors
are currently operating in extreme climatic conditions in the a
number of Middle and Far Eastern countries, providing a cost-effective
solution to drive applications in a wide range of chemical and process
industries. Monsoon Tropical Treatment is offered on all cast iron
motors including hazardous atmosphere BASEEFA certified motors -
EEx d/de, EEx e, EEx nA.

Plug-in Motors
The plug-in motor provides a simply, quick and effective electrical
connection method to install, replace, maintain or clean equipment
with rapid re-connection. The plug-in motor range is available in
aluminium construction and covers outputs from as litle as 0.07kW
up to 22kW in either 2, 4, 6 and 8 pole speeds in frame sizes W-DA63S
to W-DA180M.
Plug and socket systems are widely used throughout process industries,
such as car plants, food or pharmaceutical industries, where multi-skilled
staff are able to install or replace equipment or motors with as
little time delay as possible. Removal of equipment may be for routine
cleaning or maintenance. Other types of industry may benefit from
this method of connection where the rapid removal or replacement
of a motor is essential, due to the nature of the operating environment.
Brook Crompton has developed a simple and effective plug and socket
system in conjunction with a leading manufacturer of connectors.
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). Housings, hoods and inserts can be supplied in
a kit form to enable the modification of existing motors, details
available from Brook Crompton.

Shunt Wound Motors
The MD range covers outputs from 0.09kW to 15kW, IP20-IP55, IC01,
IC410, IC06. The MKIII range covers outputs from 10kW to 750kW,
IP23-IP55, IC06, IC0666, ICW37, A86, IC0040.Shunt motors with separately-excited
fields are the popular choice where speed control is required over
a wide range. If the field current is held constant and the armature
voltage reduced then an infinite speed range can be obtained down
to zero speed with constant torque capability. If the armature voltage
is held constant and the field current is reduced, then speed increases
over a limited range of 2:1 or 3:1 can be achieved with constant
power output capability, commutation and stability being the limiting
factors.
Field trimming can be applied in order to equally match two or
more similar motors being fed in parellel from the same armature
supply source.
