Custom or bespoke electric motors
MACCON offers a wide range of electric motors. These products or slightly modified versions thereof allow the implementation of many standard or unusual applications. However it is very common that the customer requires products from us, which are not available as standard products from the marketplace. Typically we are asked for special characteristics, such as:
- Dimensions
- Improved performance
- Supply conditions
- Special environmental conformance
- Mechanical and electrical interfaces
- Integration of several components in a new configuration or product
- Additional functionality
- Higher reliability or redundancy
For such cases, we offer customised motors, also called bespoke motors or project-specific motors. The most important custom motor categories are:

Selecting a motor technology for your application usually involves looking at not only technical aspects, but also at the cost side of things. Please contact us, to discuss your specification with an experienced motor design engineer.
Typical project plan for designing and building a bespoke or custom motor
Many customers ask us about the project duration to design and build a custom motor. Depending on the complexity, such a project usually takes about 6-9 months. You can see the individual steps of such a project in the table below. Please contact us, to discuss your technical requirements.
Lightweight motors for aviation applications
In aviation applications, the weight of the motor is critical. MACCON has specialised in designing lightweight motors for such cases. One typical example: a frameless motor weighing about 4.5kg produces a shaft power of about 13kW, running at about 3,500rpm and producing about 35Nm of torque. This particular motor takes advantage of forced-air cooling to maximise the power density of the motor. The motor reaches an efficiency (mechanical power divided by electrical power) of about 95%.
