Lin Engineering, in conjunction with Trinamic Motion Control, have announced the MiniPak. The integrated product combines a Lin size 11 step motor and a drive/control board using the Trinamic TMC222 drive chip. The NEMA size 11, 1.8° motor measures 1.1 in. square and is currently available with a length of 1.24 in.
The 211-13 model produces 9.2 oz in. of holding torque. The
TMC222-based mounted drive board, which uses an I?C interface, has a
programmable coil current of up to 800 mA, a voltage operating range
from 8 to 29 Vdc 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 daisy chain up to 32 axes. The MiniPak Designer's Kit includes the MCU board, the UBS485 as well as the necessary cables for installation.
