There are many different benchmarks in the marketplace for the sterilisation capabilities of devices. maxon motor explain the cycle and testing process for Autoclavable brushless DC motors.
maxon motor develop brushless DC motors that can be sterilised for medical and dental applications. Recently released is the new ECX range of motors with sterilisation capability on 13,16,19 and 22mm diameter versions. The new range of motors complement the existing 4 pole sterilisable 30mm brushless 150W motor and offer high speed capability up to 120,000rpm. maxon motor test the brushless motors to either 1000 autoclave cycles or 2000 cycles depending on the product. For motors with hall sensors fitted the motor is typically cycled through 1000 autoclave cycles and without hall sensors 2000 cycles. Gearheads are available with additional shaft seals. With the additional seal they are tested to 2000 cycles and without, 1000 cycles. Another new product that offers a completely sterilisable positioning system for the first time is an encoder rated and tested for 1000 cycles.
The maxon motor internal autoclave testing is carried out with the autoclave with a vacuum phase. The motors are unpacked and mounted without any additional protection. Three vacuum cycles are made at the beginning to ensure the internals of the motor become damp. The sterilisation atmosphere is built up with steam which remains constant for 18 minutes at 134˚C, 100% humidity and 2.3 bar of pressure. The unit is then cooled to 70˚C and dried. Each individual autoclave cycles takes approximately 1 hour. After 100 cycles the motors are removed from the autoclave and visually checked and motor operation is checked. Following this the motor is then removed after 250 cycles and visually checked in addition to data acquisition of the running data, motor noise, vibration and electrical strength test at up to 500V DC. Typical batch test cycles are conducted with 10 pcs and the tests are repeated with design changes. Internal testing of the motors to 2000 cycles takes approximately six months.

When prototyping for applications with extreme requirements for brushless DC motors, fast condition monitoring is critical.
Motor applications with limited space available and comparatively large power requirements can push a motor very close to burning out. In theory, it is possible to use temperature calculations for the motor winding with the help of thermal resistance rating from the motor data sheets, ambient temperatures, heat sinking details and housing characteristics. This is always considered first and then tolerances and safety margins are considered. Following this thermal modelling software and imaging can be evaluated. However some applications push a motor so close to the edge, that only real product prototype testing can be relied upon. Simply installing motors and testing how hard you can push them can also be a costly exercise and does not give enough reliable data. Actual winding temperature sensing on the motor is a solution maxon motor offer for these extreme cases. By inserting sensors through ports in the magnetic return stack and in direct contact with the winding, maxon motor can give customers a device that monitors winding temperatures without the thermal time constant delays experienced when measuring winding resistance and using housing thermal time constants.

Norwegian company Petro-Marker, developed a device that is able to collect data up to 5,000 meters underneath the seabed. The technology scans the bottom of the ocean in great detail providing information as to the location and size of oil reservoirs.
1,000 metres below the sea the environment is harsh, ice cold and very dark with no natural light. An ROV has strong floodlights that identify tri-pod objects anchored to the bottom of the seabed. These are receiver stations for electromagnetic waves transmitted into the seafloor, giving feedback on the seabed itself and finding resource deposits.
When oil companies want to find out whether drilling at depth is worth the cost, they often rely on Controlled Source Electro Magnetic (CSEM) technology. This technology utilises the differences in the electrical resistance of different bottom layers to provide signs of the location and size of oil fields. The CSEM technology uses a very strong power source to generate an electro-magnetic field, as well as several receivers to record the fields. These tripod receivers are placed on the sandy bottom and pick up electromagnetic signals that have been changed by the layers through which they passed.
In 2016 Petro-Marker placed 25 new tripods in the North Sea. What sets this technology apart is a new measuring method that uses a vertical transmitter and receiver to find resources. This enables a much more detailed resolution and data measurement up to 5,000 meters beneath the seafloor.
The tripods are about 4 meters high and made from a combination of glass fibre and special foams. Due to the sensitive electronics, metal parts cannot be used. This far below the surface, the pressure is extreme, and the salt water is hostile. At the center of the tripods (receivers), the antennas are aligned as vertically as possible on the seabed.
The system uses a maxon controller (EPOS) and a compensator. The units are encased in plastic to protect them from salt-water corrosion. Several modifications were required to meet the requirements of this application: An EC-i 40 motor, GP 42 planetary gearhead and compensator that were all customised. A dual seal, that imitates typical submarine technology, ensures the system is able to resist the enormous water pressure. The control electronics of the underwater drive are housed in a pressure-neutral glass ball that is able to resist the pressures of up to 600 bar – one of the challenges of this extreme application.
