Universal High-Voltage Gate-Driver For Up To 100A

The TMC6100 is a 3-half-bridge gate-driver for high-voltage BLDC, PMSM, and Servo motors. With a programmable gate current, it drives motors up to 100A using external MOSFETs.
Trinamic - TMC6100Micromech announces a new high-power gate-driver TMC6100 from Trinamic. The compact and cost-effective building block allows full protection and diagnostics via SPI while achieving high-speed operation with minimized switching losses in the power stage.
With a broad voltage range of 8…60V DC and programmable gate current of 0.5A, 1A, or 1.5A, the TMC6100 allows for flexible yet robust designs. Able to drive motors from watt to kilowatt, the gate-driver IC is perfectly suited for industrial drives, factory automation, lab automation, robotics, CNC machines, and finer applications such as surveillance cameras and printers.
“Integrated gate-drivers are perfect for reducing overhead cost in the design process. They not only save time and shorten the bill of materials, they also reduce design complexity,” explains Michael Randt, Founder and CEO of Trinamic. “Forming the interface between the controller and power switches, our gate-drivers improve reliability and increase robustness of the overall system design.”
Besides programmable short and overload and in-system EME optimisation to reduce electromagnetic interference to the absolute minimum, the TMC6100 offers programmable brake before make logic allowing for three or six PWM-channels. With only a few additional components, a standby-mode can be realized for energy-savings, making the TMC6100 ideal for battery-powered devices.
Its versatile interface matches simple BLDC drives with minimum requirements on the microcontroller’s PWM and PMSM control algorithms. As such, the compact gate driver chip perfectly mates any microcontroller, as well as Trinamic’s powerful TMC4671 and TMC8670 FOC controller chips.
The compact QFN package (7x7mm²) with double pin distance for high voltage operation is available from February 2020 via Trinamic’s distribution channels. Fully supported in the company’s modular evaluation system, the gate driver IC is also offered as an evaluation board for quick testing.

Success Story from Kollmorgen – Optimising Bottle Production

Kollmorgen Solution Catapults PET Bottle Blow Molding Machine to Top Producer in the World
Optimising Bottle Production
Optimising Bottle ProductionChallenge
A major bottling operation in China needed to substantially increase output in order to ensure future success in a highly competitive market. For the company’s all-electric linear PET bottle blow molding machine, productivity depends on the ability to quickly index PET preforms into position and then remove the resulting molded bottles. The company engaged Kollmorgen motion experts in early 2019 to help minimize the machine’s indexing time.
Working closely with the customer’s machine design team, Kollmorgen engineers discovered that the indexing performance requirements were overtaxing the existing motor/drive solution. The motor wasn’t able to achieve the desired indexing speed without overheating. The drive was unable to supply the necessary acceleration current and would quickly go into current foldback, further limiting the power needed to meet the desired indexing time.
The only way to prevent overheating and foldback in the existing motor/drive combination was to increase the indexing time – slowing the machine down to the point that bottle-production targets could not be met. While a larger motor might have solved the problem, the machine design was fixed and did not provide the additional space that would be needed.
Achieving faster indexing times would require more acceleration torque and lower overall inertia. Kollmorgen worked closely with the customer to evaluate the indexing goals and to co-engineer a solution that would deliver the desired machine performance improvements. A Kollmorgen 2G Motion System supplied the additional power needed to dramatically decrease index time while occupying the same space as the prior motor and drive design.
A simple, cost-effective upgrade to the 2G Motion System transformed the PET bottle blow molding machine and reinvigorated the customer’s business.
  • Motor torque increased by 30% without an increase in size.
  • Faster acceleration reduced the indexing time from 1.6 seconds to 1.3 seconds, a 23% improvement.
  • No machine modifications were required to fit the AKM2G servo motor onto the existing motor mount, saving the customer design and documentation time.
  • The machine now produces 156,000 bottles (600 ml) per hour, making it the #1 bottle producer in the world.
As a Gold Partner, Micromech are able to supply and provide expertise on Kollmorgen products. Contact our sales team on 01376 333333 or sales@micromech.co.uk for price and delivery or technical assistance.

Introducing the Commander core, a powerful hybrid IC motion controller for OEMs

Micromech is pleased to introduce Nippon Pulse’s Commander core motion controller, a four-axis hybrid IC that bridges the gap between off-the-shelf and design-from-scratch controllers. The Commander core is secure, flexible and is easily scalable from prototype to production while remaining cost-effective for high-volume applications.

Nippon - CMD-4CRUsing the Commander core during the development of your applications helps reduce development time due to its ease of use, resulting in a faster path to market for your design. Commander uses a BASIC-like programming language (A-SCRIPT) that allows programmers to compile, read and write standalone programs. The software also provides multi-threading and subroutine support, and can be run in both PC-based and standalone modes.

Commander core’s advanced functionality includes linear, arc, circular, helix and tangential interpolation, as well as coordinated motion and continuous buffered motion, thanks to its 100 buffer registers. It also allows the user to choose between trapezoidal or S-curve acceleration/deceleration, and absolute or incremental positioning. Changes can be made on-the-fly as well, with either the speed or target position shifting as desired during operation.

The Commander core is based on Nippon Pulse’s PCL6045BL motion control LSI, and an ARM Core processor. It has stepper and servo motor interfaces, and can operate via joystick with analog input (X and Y axes). Communication to theCommander core can be established over USB, Serial (RS-485, I2C, SPI), and Ethernet.

The Kollmorgen AKM2G series range of AC Synchronous Servo Motors from Micromech

To compliment the existing AKM Range there is the AKM®2G for demanding applications that the standard AKM cannot meet.

  • Smaller footprint helps to reduce machine space
  • Increased torque provides higher performance
  • Wider speed range for faster operation
  • More options provide greater flexibility
  • Higher efficiency due to reduced energy consumption
The latest generation of synchronous servo motors from Kollmorgen feature design sizes with performance levels between 0.3 and 10 kW. With continuous torque increases of up to 30% versus traditional servos, Machine builders and OEMs can substantially increase machine throughput and proficiency without increasing the mounting size of the motor. AKM2G is also designed to support a wider array of standard options including: feedback, brake, thermal sensor and seal options.

Kollmorgen AKM2G

For new machine designs, the AKM®2G motor allows customers to decrease the size, footprint, and complexity of the machine, while still getting the power and performance required.

The compact AKM®2G drops into existing machine designs to increase performance, when compared to other manufactures motors, without increasing the size of the motor.

What is the differences between AKM2G and AKM?

While AKM and AKM2G both leverage certain design elements and best practices in production, they are very different motor designs. The AKM2G utilizes an alternative electromagnet design, capable of increased continuous torque output per motor size. Another key difference is the motor housing. AKM uses a two-piece housing design: Front Endbell/Housing + Rear Endbell. The AKM2G uses a three-piece housing design: Front Endbell + Housing + Rear Endbell. This allows for more flexibility in offering custom mounting features without significant tooling investment.
