Hybrid step motor

Transformed into a step-less servo motor

Technosoft (Switzerland) has released an additional member of their iMOT line of motors with integrated motion controller and drive: the iMOT172S XM-CAN step-less motor. It offers two CAN versions for communication.

THE PRODUCT IS BASED ON A HYBRID STEP MOTOR, on which a magnetic encoder was integrated, together with a member of the iPOS motion controller series. The drive was built into a compact package measuring 42 mm x 42 mm x 70 mm. For reliability, the design is made with only one PCB incorporating the encoder and the iPOS controller that utilizes the Technosoft Motionchip technology and provides seven I/Os. The configuration, tuning, and local programming of the drive can be done using the graphical platform Easymotion Studio. The position sensor is absolute single-turn, providing 4096 counts per revolution for accurate speed, and position control, down to 5 arc minutes.

While an Ethercat version is under preparation, the current release covers two CAN versions: the standard CANopen, in accordance to the CiA 301, CiA 305, and CiA 402 protocol, and the TMLCAN protocol. TML (Technosoft Motion Language) opens the possibility to use the motion controller, allowing it to operate as an independent intelligent device. As an example, any homing routine can be customized to match the application needs. Standalone single- or multi-axis applications with communication between drives without the need of a CAN master are possible, while various types of CAN masters are supported through an set of Motion Control Libraries.

This step-less motor reaches a peak torque of 500 mNm at 1000 revolutions per minute without a gearbox, achieved from a motor with a square flange of 42 mm. The maximum length of the integrated unit is 70 mm. Efficiency is obtained through the implementation of current and torque vector regulations under a field oriented control method (FOC) that transform the motor into a step-less servo motor, reducing the current consumption and heat dissipation typical to hybrid steppers. The NEMA17 flange ensures multiple sources of gearheads that are available for fitting to the motor, depending on the requirements of the application.
