Brushless flat DC motor with hollow bore for air and light transmission.
Today we exhibit a new motor development featuring a Brushless DC (BLDC) flat motor. Flat motors are also commonly referred to as pancake motors. This unit has a body length of just 38mm and an output power of over 157W and 6000rpm at the shaft in the application. The average motor power rating for the series across 6 variants is 100W. The overall motor diameter is 68mm and it can be supplied with or without protective covers for IP rating. The motor is available with an internal encoder with resolutions up to 16,384qc per revolution making it suitable as a rotary stage of robotic joint actuator. The unique feature though is the motors hollow shaft. This is to enable customers to pass light or air through the bore of the motor. Air transmission is a common requirement for packaging and placement machinery and light or fibre is a common requirement for film and camera gimbal applications. This motor was also manufactured with the customers shaft length and bore specifications in combination with a custom rear shaft extension at the rear from the motor rotor.

First maxon motor of its kind. Brushless DC motor with hall sensors, absolute encoder and incremental outputs
For fine motor position control across multiple generation brushless motor controller models, maxon motor Australia has supplied the first of its kind maxon EC-max brushless DC motor with three modes of feedback.
The new micromotor encoder 16 Easy Absolute 16mm x 9mm offers high resolution motor feedback from a tiny package. Additionally it offers 4,096 counts per turn incremental outputs with line driver channels and an index pulse. The Absolute output is available in the choice of Binary BiSS-C or Gray Symmetric SSI. The encoders use an interpolated hall sensor angle measurement system to generate the incremental quadrature output signals according to EIA-422 with 20mA maximum current draw and ESD protections built in. The angle value zero of the encoder is factory aligned with the BLDC motor zero point and the encoder is welded in place on the rear flange of the motor. When fitted with a multi pole brushless DC motor the encoder can still show the angle values zero once per mechanical turn and the angle zero is identical to the index position. The motor itself also contains three hall sensors for commutation purposes. An adaptor is available to convert the single ended clock and data signals of the absolute encoder into TIA/EIA RS422 compliant differential clock and data lines.

This small brushless DC motor displays the advanced miniature and micro motor manufacturing techniques of maxon motor. So small are the details it is hard to capture the modifications and quality. The example pictured is a 10mm diameter DC motor and planetary gearbox fitted with an encoder for speed and position control.
What’s new? Sure there are a lot of small DC motors available now days however it’s in the detail that defines the difference between motors. Pictured is maxon motors newest planetary gearhead range that has been selected because of its stainless steel construction. The body and flange of the gearbox are one piece allowing the design engineers to not only create a mounting flange specific to the mounting footprint available in the application, it also allows maxon motor to orientate the gearhead flange with the motor cable exit. Enabling a shorter cable and neater cable looms. Laser welding of the motor flange is also a technology that is used to affix a customer specific drive pinion to the shaft. This gives the strongest possible power transmission coupling in these miniature sizes. maxon motor provide its customers with complete drawings and models for appraisal before samples are manufactured even for non-standard DC motor and gearhead assemblies like the shown example.
The new 10mm gearhead can supply torque levels up to 200mNm and can operate with input speeds up to 15,000rpm. Standard supply is with stainless steel ball bearings, it has efficiencies as high as 90% and weight as low as 6.7g.

Maxon motor have developed their most powerful DC motor positioning controller to date.
With a maximum power output of 2.1kW maxon are pleased to announce the release of the EPOS4 70/15 DC motor positioning controller. The CANopen controller with an EtherCAT option is presented in a robust metal housing. Suitable for both brushless and brushed DC motors the positioning controller is a cut above the rest due to its ease of operation and broad operative scope. The various digital and analogue connections can be configured and the unit is suitable for use with a wide variety of feedback systems. It can also be integrated into various master systems. This new product and many more will be showcased at the Hannover Messe in Germany from 23-27 April. For more information please contact maxon motor Australia tel. +61 2 9457 7477.
There are additional connectivity options with maxon’s positioning controller, the EPOS4.
The addition of an expansion board now allows maxon positioning controller, the EPOS4, to be integrated into any EtherCAT network as a slave using the CoE standard (CAN application layer over EtherCAT). The EtherCAT card developed for this use can be combined with the EPOS4 controllers in a housing, as well as with all EPOS4 modules. The benefits widen the applications where compact positioning controllers are needed, for example where short cycle times are important in synchronized multi-axis systems.
EPOS4 controllers are suitable for controlling both brushed and brushless DC motors. They are known for their high power density and excellent value for money. For more information about maxon’s EPOS controllers, please visit epos.maxonmotor.com or tel. +61 2 9457 7477.
This new combination of motor and gearhead can produce stable speeds over 120rpm with 10Nm applied.
With a very flat speed torque ratio the 40mm 170W brushless DC motor from maxon motor is suitable where minimal speed reduction is required under load. Particularly apt for process machinery or food production equipment where 24/7 continuous use regulated speed control is necessary. The pictured unit features a 2000qc incremental encoder and a 66:1 planetary gearhead. The output shaft is sealed and the unit can operate in small enclosures via conduction cooling. Brushless operation and ceramic components also give durability and robustness to the combination resulting in increased lifespan.

An integrated approach in a decentralised world. maxon brushless DC motor with internal position controller and encoder.
Particularly suitable for manufacturing lines and process control applications the maxon integrated drive features a maintenance free combination of a 54 mNm 12, 24 and 48V brushless DC motor, 4000qc 3 channel incremental encoder with line driver (complimentary channels) and a full digital position and speed control unit. The position control is offered in two versions. One with internal processor and memory for pre-programming and standalone position control operation. This unit also has CANOpen master functionality. The second version is a CAN slave unit. Multiple integrated drives can then be daisy chained off the first and a complete standalone coordinated multi axis drive network can be configured. Alternatively the slave drives can be connected directly with a PLC or FPGA based master. The motor units are supplied with the powerful EPOS studio tool for easy gain configuration and motor tuning. Standardised IEC 61131-3 simplifies development and reduces costs. Planetary gearheads are available in a piece part system allowing adjustment for required application speed and torque.
