BLDC Brushless Flat DC motor sideview450px BLDC motor Brushless Flat DC motor450px

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.

Brushless DC flat motors – in parts.

BL Frameless DC motor + encoder 450px

maxon motor Australia’s new frameless DC motor and encoder set allows even further miniaturisation and integration. The new motors meet the increasing need for smaller robotic actuation by assembling individual parts directly into the robotic joint.

This is the new frameless brushless DC motor (BLDC) with a diameter of 45mm and an assembled depth of just 23.7mm, it has a continuous rating of 50W. 70W and 130W versions are also available. The frameless design is particularly suitable for processing machine or rotary stage manufacturers who need a large through bore to pass cabling or tubing. For positioning a high resolution magnetic encoder ring also with the same bore as the motor rotor is also supplied as components. The encoder ring is marked with the zero position to allow alignment with the motor zero commutation point in the application and is available in IP rated, absolute and incremental options. The combination gives a low profile large bore positioning system made up from standard parts with shorter lead times than specialty manufactured complete assemblies. The second advantage is for space saving in applications already containing joint actuation bearings or mounting systems there is no need for a second set within the motor.

First maxon motor of its kind. Brushless DC motor with hall sensors, absolute encoder and incremental outputs

BLDC motor w hall sensors, absolute encoder +incremental outputs 450px

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.

EC45_flat_70W_Kabelversion_411812_450px

Driven by customer demand, maxon release modifications to their flat / pancake motors.

maxon motor have altered the EC45 and EC90 flat BLDC motors. Now with the option to add cables with a pre-mounted connector by default and in combination with the integrated MILE encoder. The motors offered are the EC 45 flat in 50 & 70 W versions or 30 W by request. The EC 90 flat 160 W and 260 W is now available in cable version. The cable versions feature a much smaller footprint by eliminating excess PCB overhang from the side of the motor.

The flat design of the brushless DC flat motors makes them ideal for many applications, particularly robotics and industrial automation. Offering internal or external rotor motors, the flat BLDC motors are perfect for when space is limited being small and lightweight but with powerful torque. The simple and considered design means that production is largely automated, keeping prices as low as possible.
