IP65 DC motor with encoder, brake and gearbox.

First Delivery of KAG IP65 DC motor, gearhead, encoder and brake combination with gasketed flanges and rubber sealed bearings. Suitable for harsh operating environments, transportation and agriculture applications.

Pictured below is the first example of the Kählig Antriebstechnik M80x80 24V 128rpm DC motor + 24V holding brake, digital encoder and 81mm 25:1 planetary gearbox. All the individual components have been specially flanged and gasketed for sealing against moisture and particles to IP65. This particular example was from the first shipment in Australia and supplied for an Agricultural application. Though it is also suitable for machining and process control applications with harsh environments. The robust nature of the product also has advantages for the transport industry, in particular, automatic trailer covers. The combination and sealing process is available on all KAG motors with suitable flange area for an O-ring groove and gasket combinations and are modified on request. Featuring robust and reliable German-built quality at a competitive cost the KAG IP rated motors are proving popular in Australia.

New high resolution encoder for DC motors and when to use them

maxon motor release its new ENX 16mm RIO encoder with 65,536 counts per turn for DC motor applications requiring fine positioning and constant velocity.

This new encoder has been released with 262,144 quad counts per revolution. But where to use resolutions not seen in such a tiny size encoder? An example would be pick and place machines for the placement of electronic components during pcb manufacture. New microprocessors and FPGA devices can have up to 2601 contact points on a 0.4mm grid. The pick and place machine for this part would need a controllability of nine hundredths of a revolution and the accuracy would require an encoder to be fitted to the positioning motor with ten times this amount. Also applications with demanding constant velocity requirements require high resolution encoders. Enabled by continuously increasing processing speeds new high resolution encoders vastly improve the feedback loop. Each example requires the high resolution and also error free signals at high speeds. The RIO is an Reflective Interpolated Optical design that allows cor compact dimensions of 16mm diameter and 7mm length. Output signals are RS422 differential including an index pulse. Delta robots, Precision manufacturing tools, 3D printers and the semiconductor industry can all benefit from this new product.

Technical report on energy efficiency in small DC motors

The maxon academy have released a new two part technical report into the energy efficiency of small DC motors, micro drives and subsystems.

The maxon motor academy headed by Dr Urs Kafader provides acclaimed technical reports, educational textbooks and technical training on all aspects of DC motor drive systems and associated control devices. The latest technical document authored by maxon motor technical trainer Jan Braun focuses on energy efficiency and highlights how motor efficiency requirements have affected the design of many products. Application examples and selection processes are given throughout. Topics include motors operating in the no-load range, motors operated at standstill, control, load mechanics, pulse width modulation and motor chokes. In an increasingly battery powered and greener world high efficiency design and the correct selection of components are becoming more and more important. maxon motor strives to further educate not only its own engineers but also the designers of the future. Contact maxon motor Australia for a full copy of the technical report and other resources that are available from the maxon academy. Ph: +61 2 9457 7477.

New IP67 12V and 24V DC motors with internal encoder and holding brake.

Supplied via maxon motor Australia, specifically designed for the Agriculture industry is the first of the new IP67 12V and 24V DC motors with an incremental encoder built inside the motor body.

The first motor in this series being developed is the 80mm diameter 172mm long 250W brushed permanent magnet motor assembled with 81mm IP67 gearheads. The IP67 gearhead range has an large reduction range to select from facilitating torque production of up to 180Nm. The internal magnetic encoder sits behind the motor commutator, has two channels and can be run on either 5V DC or 24V DC. Mounting the encoder internally also has the advantage of freeing up the motor rear shaft where an external holding brake can be fitted. The first units supplied will have a B56 brake that combined with gearing can provide the 180Nm of torque also for holding the load in place on the unpowered condition. Future versions will have the option of either power activated or power de-activated holding brakes also with a sealed enclosure for harsh environments.

Zero Backlash gearhead and DC motor assembly.

Achieving a combination of zero magnetic cogging and zero backlash in a 24V gearmotor assembly.

This new motor and gearhead from maxon motor Australia achieves over 60Nm on a continuous basis at only 10A current draw with a 24V DC supply. New achievements in the 94% efficient motor which features a coreless zero cogging winding (detent free) coupled with a zero backlash gearhead that features high stiffness levels make the drive suitable for robotics and process applications that require completely smooth motion with high power density. Sealed and lubricated for life the combination can handle harsh industrial environments and a -30 +100C ambient temperature range. Gearhead ratio reductions up to 160:1 can also be multiplied by large amounts by stacking planetary input stages and high resolution encoders allowing for accurate positioning tasks. maxon motor Australia now have the ability to configure zero backlash solutions to suit the application requirements.

maxon DC motors drive natural beauty treatments.

A recently patented technology uses maxon DC motors to help people look their best.

endermologie® is a beauty therapy, cell stimulation procedure, created by French company LPG nearly 30 years ago. Initially developed to treat scar tissue and aid in the skin’s healing process, it became apparent that this treatment served twofold. Use of the instrument led to tighter, supple skin, and a reduction in cellulite and fat cells in the hypodermis. Today, approximately 200,000 people in 110 countries undergo treatment with LPG technology every day. Recently LPG launched a new version of this technology announcing the Endermolift method. Organically reactivating skin cells’ processes, this 100% natural, non-invasive, non-aggressive mechanical skin stimulation technique works by applying suction to the skin by the head of the device. Stimulation is brought about by two pulsing flaps, whose beat frequency can be adjusted by the therapist. In the machine is a maxon brushless DC motor and planetary gearhead. The gearhead was customised with the addition of plastic parts to minimise the noise level. The DC motors were selected for their quiet operation, reliability, torque, speed and long service life.

New top of the range compact DC motor encoder

A 16mm encoder from maxon for precise positioning and control of DC motors.

Maxon encoders allow for precise position and velocity control of DC motors. The latest release is a top-of-the-range high-resolution encoder, the ENX 16 RIO (Reflective, Interpolated, Optical). This encoder offers an impressive resolution of up to 65,536 counts per turn in a casing that is robust and compact. The resolution can be configured at the factory, that is particularly useful where the DC motor combination is tailor-made and then resolution can be refined to the respective motor. With 16mm outer diameter and 7mm overall length, the housing is mechanically tough and protected from dust due to its injection-moulded construction. The encoder operates at temperatures ranging between -40 °C to +100 °C.

Requirements on encoders are becoming more and more demanding. This applies particularly to positioning applications with precision constant-speed control, where increasingly compact housings need to accommodate an ever greater number of electrical connections. The encoder can be configured with matching maxon DC motor and gearhead combinations online. It fits the new brushless EC-i 30 motors and the brushed DCX motors (with 16mm diameters plus). The counts per turn and the electrical interface of the encoder can also be configured specifically.

For more information on the encoder combination options and specific product information please call maxon motor Australia tel. +61 2 9457 7477.DCX16S_ENX16_RIO_450px.jpg
