Electric Motors International specialises in the rapid supply of replacement electric motors for ships worldwide.

Our core business is to supply electric motors for ships on an urgent or non-urgent basis. We have access to stock around the globe including our own brand of equipment (EMI-MOTORS™). We have a very efficient logistics department conversant in dealing with ships.

We are usually able to get your ship moving by using local stock. We are well aware that to select the correct replacement motor is only part of the job: it needs to be delivered on time as well. We are able to ship motors 24hr/day, including at weekends.

Electric motor repair and modification

Our workshop is able to modify motors very quickly, such as turning down and shortening shafts. This enables us to replace Japanese standard motors with European motors. We also manufacture couplings to compensate for shaft diameters on European motors that are smaller than Eastern standards demand them to be.

We provide high-efficiency aluminium electric motors.
Should we need to turn down a shaft, a very fast turnaround of less than 24hr is achievable.
We offer heavy-duty cast-iron electric motors.
IP 23 electric motors are very often used for inert gas blowers.
We offer explosion-protected electric motors for all types of ship.

Electric motors for pumps, boilers and blowers

Our electric motors can be used to replace more expensive brands such as ABB, Leroy-Somer, Siemens and many more. They can be used for all kinds of machinery, pumps, boilers, blowers, etc. We also supply Siemens / Mez motors at competitive prices.

Generally we quote 50%-60% below motor makers’ standard pricelists. Our staff and suppliers are fully trained in the electromechanical area. We supplement that with drawings for double-checking the measurements.

Motors for ship building and conversion projects

Should we need to turn down a shaft, a very fast turnaround of less than 24hr is achievable. We can also have a new motor made with very short delivery times.

We can supply a full range of motors made to order or from stock, depending on the urgency.

Should you wish to purchase a larger amount of motors for a ship conversion or dry docking we can offer very fast delivery and low prices. All motors can be made according to the rules of GL or similar societies. A full survey of motors can also be arranged.

Aluminium electric motors

The key benefits of our high-efficiency aluminium motors are:

  • IEC size 56-160, ISO F (B-rise) IP55
  • Removable feet
  • B14 / B34 large up to size 132
  • Available with Temporiti brake for size DMA2 56-132
  • Available with right or left-hand side terminal box for size 80-132
  • Quality bearings (SKF, FAG and NTN)

Cast-iron electric motors

The key benefits of our heavy-duty cast-iron electric motors are:

  • Standard PTC 150°C thermal protection set
  • IEC size 80-450, ISO F (B-rise) and IP55
  • Efficiency class 2 (class 1 available on request)
  • Available with right or left-hand side terminal box for size 80-315
  • Available with brake
  • Two-speed and multispeed motors available
  • Quality bearings (SKF, FAG and NTN)

IP 23 motors

IP 23 motors are very often used for inert gas blowers, as it is possible to generate more power from an IP 23 motor compared with a frame-sized motor. This is very handy where there is limited space.

Explosion-protected electric motors for hazardous areas

Explosion-protected electric motors are used on all types of ship. It is very common to use EEx(e) motors for areas on a ship with a potentially explosive atmosphere containing inflammable fumes (i.e. gas tankers, cargo pump rooms, paint stores, etc.).

These explosion-protected electric motors are three-phase asynchronous electric motors with a shot-circuit rotor, certified according to CENELEC EN 50014, EN 50018 and EN 50019 (IEC 79-0 and IEC 79-1).
