Brushless DC motors for down hole and directional drilling.

Directional Drilling

Directional Drilling

The recovery of petroleum and natural gas requires constant innovation and improvement of technology. This technology used for deep drilling processes are exposed to extreme environmental conditions. Temperatures of 200+°C, high pressure and extreme shock and vibration. Brushless DC motor technology from maxon motor is utilized in various drilling applications, hydraulic valve control, communication mechanisms and measuring instrumentation.

Today over 85 percent of the world’s energy use is based on fossil fuel sources such as coal, oil and gas. However, reaching these resources requires the need to drill deeper than ever before which is not a simple exercise. Down hole deep drilling equipment opens the possibility of recovering resources from depths greater than 2.5km. Recent developments allowing down hole drilling equipment to be directionally controlled has given access to formerly inaccessible oil reserves. Now drilling to 5km down and 11km across is even possible.

Extremely tough environmental conditions are commonplace globally for drilling equipment, the demands on the drill head in particular are at their highest. Brushed and brushless DC motors need to withstand the intense vibration, pressure and heat. The heavy duty brushless DC motor range produced by maxon motor are not only designed for but are rated and tested to meet these conditions. Combined with new electronics technology they allow for improved control and monitoring of drilling procedures.

Mud flow power and more.

Using magnetic couplings a back driven motor becomes a generator. Using the mud flow for the drill turbine the brushless DC motor power is then harnessed for localized electronics in the drill head avoiding the need for batteries. The drill head position can also be detected and adjusted on the fly. This process is called Measurement While Drilling (MWD). This technology converts sensor data into pulses that are transmitted to the drilling platform. maxon heavy duty motors can actuate the mechanism, forming the communication pulses. maxon heavy duty DC motors also actuate hydraulic valves within the drill head.

maxon heavy duty motors are also available with corresponding gearboxes. The gearboxes are manufactured with the same extreme operating environments in mind. The applications typically require elevated torque for very low duty cycles. For example: Generating the mud pulses and actuating the hydraulic valves. A unique feature of the heavy duty gearbox is the through holes in the gear housing. These are ports that allow the gearhead to be submerged in oil and they facilitate the possibility for oil to circulate through the gearbox and provide elevated heat-sinking. The heavy duty DC motor also contains the oil ports and may also be used submerged in oil or in free air. The gearmotors are manufactured entirely without structural adhesives giving it the capability of withstanding extreme temperatures. This is also of particular importance when using the motor in vacuum conditions avoiding the contamination of the vacuum via outgassing. The heavy duty motor range is designed to withstand temperatures over 240°C at pressures up to 1,733 atmospheres. They can withstand vibrations to 25 Grms, impacts to 100 G.

High efficiency DC motors at great depths
The maxon heavy duty motor range features efficiencies of up to 88% in air and over 70% submerged in oil. This makes it an ideal solution for any extreme environment such as aerospace and heavy industry. They have zero cogging making them easy to control and suitable for precise positioning.

maxon’s ESCON Controllers

Roger Hess, Sales Engineer, discusses maxon’s line of ESCON motor controllers. These controllers were designed for dc brushed and brushless motors. You can configure the drive using maxon’s ESCON studio.

maxon presents new High Torque DC brushless motors

maxon's NEW EC-i 40 DC brushless high torque motor

maxon’s NEW EC-i 40 DC brushless high torque motor

For applications demanding very high torque, drive specialist maxon motor is now launching its EC-i 40 DC brushless motor in a High Torque version. The iron-core internal rotor drive is available with a diameter of 40 mm and delivers up to 234 mNm of torque.

When it comes to powerful movements, maxon delivers with its EC-i 40 High Torque series of DC motors. The Swiss drive specialist presents three powerful iron-core internal rotor drives. The drives have a diameter of 40 mm and are equipped with an innovative rotor. They feature high dynamics, a low cogging torque, and extremely high output torque. The strongest motor in this series offers a maximum nominal torque of 234 mNm and is 56 millimeters in length. It exceeds the performance of its precursor model by up to 70 percent.

Especially suitable for robotics

The three new brushless DC motors are cost-effective and ideally suited for applications in robotics, prosthetics, and industrial automation. The compact design offers a great solution in applications with extreme space constraints. When needed, the EC-i 40 High Torque motors can be combined with maxon gearheads, servo controllers, or position controllers. The EC-i 40 series is easily configured and available in our online shop. Shop.maxonmotor.com

MAXPOS 50/5 Wins Product of the Year

Medical Design Briefs - 2014 Product of the Year

Medical Design Briefs – 2014 Product of the Year

High performance positioning controller

Medical Design Briefs magazine, targeted to medical product design engineers and managers, provides readers with the latest advances in technology, materials, and regulatory issues.

Each month, Medical Design Briefs magazine publishes a Product of the Month deemed to have exceptional technical merit and practical value for its design engineering readers. At the end of the year, readers are asked to vote for one among the 12 Products of the Month that they feel was the most significant new product introduced to the engineering community in 2014.

“This year, maxon precision motors’ MAXPOS 50/5 high-performance positioning controller was a top vote-getter, earning this prestigious honor,” said Beth G. Sisk, Editor of Medical Design Briefs. “We are very proud to present the Product of the Year award to maxon precision motors for providing motion control technology that allows manufacturers to create the next generation of effective, efficient, and safe medical products.”

maxon launches New Products

EPOS2 Positioning Controllers support additional Platforms.

The maxon motor EPOS2 motion controllers for DC brushed and brushless motors are enhanced by even more possible fields of applications. Deployment of computer-based drive control rather than traditionally used PLC systems are becoming more and more prevalent in practice. To stay ahead of this trend, maxon has updated the EPOS2 libraries to support CANopen interfaces from Kvaser and NI-XNET, in addition to our existing solutions (NI, IXXAT, Vector). In additon, new opportunities unfold for computer platforms with serial communication via USB or RS232 under Windows or Linux. The existing libraries for Intel/AMD (Windows 32/64-Bit, Linux 32-Bit) are further extended with a Linux 64-Bit version. Additional support of 32-Bit ARMv6/v7 solutions allows the broad scale use of trend platforms, such as Raspberry Pi or BeagleBone. True to the principle “Easy-to-use POsitioning System”, simple and fast incorporation into a wide range of solutions with extended, no cost, libraries is supported.

With today’s controller architectures a variety of motion control components from various suppliers are used. Therefore, easy integration into the superior master system plays a crucial role in the success. By means of extensively documented maxon libraries, integration of EPOS2 slave drive controllers takes no time and makes elaborate interface programming obsolete. Customers can fully focus on their main task; the development of their application. A wide range of supported systems permit a selection of the ideally suited master.
