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.

Smart Driver IC for Battery Powered DC Motors

Trinamic’s TMC7300 is the company’s second IC for low-voltage applications. The power driver with UART-based control for torque and velocity can drive up to two DC motors from 2 (1.8)…11V DC.

trinamic_ic_tmc_7300Micromech announces the TMC7300 from Trinamic, a low-voltage driver for one DC motor up to 2A peak, or two DC motors up to 2.4A peak. Operating on a single or dual Li-Ion cell or at least 2 AA batteries, the TMC7300 is optimal for battery-operated equipment such as IoT and handheld devices, printers and POS applications, toys, cameras, and mobile medical devices.

Thanks to an integrated direct bridge, the chip can also be used to control solenoids, relays, and other actuators. Despite the small form factor – a QFN of 3×3 mm² with 20 pins in total, the TMC7300 scores with a high power density using integrated power MOSFETs and a complete integrated DC motor control logic. As such, it can control velocity and limit torque, or be used in torque-controlled operation.

Michael Randt, Founder, and CEO of the Hamburg, Germany based company, explains: “By rolling out our new family of driver ICs for battery-powered applications, we want to stimulate innovation. We want to fuel the imagination of engineers around the world by giving them the tools needed to develop new applications and turn proven concepts into portable devices that are convenient to use for both consumers and professionals.

For ease of use, the TMC7300 comes with a single-wire UART interface. Up to two DC motors can be controlled through it for direction, velocity, and torque. Together with Trinamic’s development environment, including open-source hardware and software, the new chip allows for rapid prototyping at reduced overhead cost.

Protection and diagnostic features support robust and reliable operation, including PWM control for smooth acceleration and deceleration, an internal current limiter to protect both the DC motor and power source and mechanical load sensing. Part of the diagnostic features, the chip detects errors including short detection and overtemperature. Once detected, the TMC7300 can disable the power stage and report the error via the interface or DIAG output.

Together with the breakout board TMC7300-BOB and the evaluation board TMC7300-EVAL, the TMC7300-LA will be available from end of January 2020.

Features and Benefits:

  • Voltage range of 2 (1.8)…11V DC
  • Driver for 1 DC motor up to 2A, or 2 DC motors up to 2.4A
  • Battery operation with 1 or 2 Li-Ion cells, or at least 2 AA batteries
  • Single-wire UART with velocity control, torque control, and direction
  • Standby current draw of <50nA (typ.)
  • Low RDSon with LS 170mΩ & HS 170mΩ (typ.)
  • Full protection and diagnostics, including motor load feedback
  • PWM control of LEDs
  • Suited for solenoids
  • QFN20 package (3×3 mm)
