The Minipak combines a Lin Engineering size 11 step motor and a drive/control board using the Trinamic TMC222 drive chip, making it the perfect combination for small applications.

New from Servotechnic, the Minipak combines a Lin Engineering size 11 step motor and a drive/control board using the Trinamic TMC222 drive chip, making it the perfect combination for small applications.

The Nema size 11, 1.8 degree motor measures a mere 1.1in square and is currently available with a length of 1.24in.

It provides high torque in a small package.

The 211-13 produces 65mNm of holding torque.

The mounted drive board uses the TMC222 which features an I2C interface and has a programmable coil current of up to 800mA, a voltage operating range from 8 to 29V DC and is capable of 2x to 16x microstepping.

The driver board contains a fixed frequency PWM current control with automatic selection of fast and slow decay mode as well as a built-in ramp generator for autonomous positioning and speed control.

Another convenient feature is the ability for on-the-fly alterations of target position.

The MCU unit, which is sold separately, adds RS485, homing, two-module handling, parameter storage, constant velocity mode, two demo modes, and ASCII interface.

When the Minipak is used along with the MCU board the user can daisychain up to 32 axes.

For the ultimate convenience, the Minipak Designer's Kit includes the MCU board, the UBS485 as well as the necessary cables for easy installation.

Industries which may find the Minipak Series a perfect fit are medical, robotics, semiconductor and communications.
