New DC motor technology released from maxon.

maxon motor is introducing new miniature brushless DC motors, brushless frameless motors in kit form and EtherCAT positioning controller solutions.

A number of new products are released from DC motor drive specialist maxon motor. More configurable brushless DC motors (from the ECX SPEED range) in both Standard and High Power options are available with diameters of 13mm and 19mm, along with matching planetary gearheads and encoders. This brushless DC motor has very high speeds and is particularly suitable for power tools and demanding speed & positioning control tasks. All components can be configured online. These customised drives are assembled using automated processes and are ready for shipping after no more than 11 working days.

Newly released is the popular high-torque powerful brushless flat DC motor available in a frameless kit. This means that the stator and rotor are delivered separately and joined only during the assembly of the device. This brushless frameless kit is especially suitable for robotics applications where space is constrained.

Maxon have also developed their compact EPOS4 positioning controller to be equipped with an EtherCAT expansion board for integration into any EtherCAT network.

These innovations are on display from November 28 to 30 at the SPS IPC Drives exhibition in Nuremberg, Germany.

New 30mm brushless DC motor range

maxon motor have released a new range of 30mm diameter brushless DC motors in versions that offer increased torque or increased speed.

The new range will initially consist of 4 power versions ranging from 30 to 75W. They feature uncompromised quality with all stainless steel laser welded flanges and body. Stainless steel large dimension preloaded ball bearing system and a hardened stainless steel shaft. They integrate into the maxon modular system with a range of encoder and gearbox selections allowing engineers to create a dedicated mechatronic solution for each application. The range uses the latest production technologies offered by maxon motors new manufacturing facility in Korea which achieves a cost competitive solution suitable for general automation, power tools, seat actuators and process control machinery. Maximum speeds of 15,000rpm and selectable winding configurations allowing for use on 12V, 24V and 48V DC systems add versatility and this is coupled with torque levels over 100mNm from a 30mm diameter motor. These features give the new product series a unique offering compared with traditional maxon brushless DC motor products, further expanding application possibilities.

New Autoclavable brushless DC motor range and sterilisation cycles.

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.

Brushless DC motor – pushing it to the limit

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.

Exploring hidden depths under the seabed.

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.
