LIN Engineering in conjunction with Trinamic Motion Control have released the MiniPak. This integrated product combines a Lin size 11 step motor and a drive/control board using the Trinamic TMC222 drive chip, making it the perfect combination for small applications. The MiniPak is available in Australia from Switches Plus Components.
The MiniPak is now comes in three motor stack lengths of 1.24", 1.75" and 1.99" that allow for higher torque. The available holding torque ranges from 9.2 to 16.6 oz-in depending on the stack length. It is also available in longer stack sizes.
The mounted drive board, which uses the TMC222’s I²C interface has a programmable coil current of up to 800mA, a voltage operating range from 8Vdc to 29Vdc and is capable of 2x to 16x microstepping.
The driver board contains a fixed frequency PMW 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 and ASCII interface.
When the MiniPak is used along with the MCU board, the user can daisy chain up to 32 axes.
For the ultimate convenience, Lin Engineering is also offering the MiniPak Designer's Kit, which includes the MCU board and the UBS485, plus the necessary cables for easy installation.
Industries that may find the MiniPak series a perfect fit are medical, robotics and communications.
