Maxon develops custom brushless DC motor for Diamond Light Source monochromator
Maxon Motor has developed a customised ‘high-vacuum’ brushless DC motor for Instrument Design Technology for use in the Diamond Light Source particle accelerator in Oxfordshire.
The motor has been used in the synchrotron’s new double crystal monochromator, which is helping scientists understand the Earth’s climate, atmosphere and volcanic activity before the birth of humankind.
Maxon redesigned its brushless, stainless steel EC22 heavy-duty motor — originally intended for subsea oil applications. Instead of epoxies, the engineers assembled the motors using micro laser welding.
Key benefits of product application
- The motor has delivered high performance and excellent reliability.
- It is tolerant of extremely high temperatures — this has been essential as the high vacuum would make dissipating heat by convection impossible.
- The construction of the motor means it is not susceptible to outgassing.
