Technosoft, based in Neuchâtel, Switzerland, has released the first member of its iMOT line of motors with integrated motion controller and drive — the iMOT172S XM-CAN intelligent stepless motor.
The product is based on a cost-effective hybrid step motor on which the motion control specialists at Technosoft have integrated a magnetic encoder, together with a member of their powerful iPOS motion controllers, into a very compact package (42 x 42 x 70 mm).
The design is made, for high reliability, with only one PCB incorporating the encoder and the iPOS controller that utilizes the Technosoft MotionChip technology and provides 7 I/Os. The configuration, tuning and local programming of the iPOS drive can easily be done using Technosoft’s powerful 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, 305 and 402 profiles, and the TMLCAN protocol. TML (Technosoft Motion Language) opens the possibility to use the powerful 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 as well supported through an extended set of Technosoft Motion Control Libraries.
This intelligent stepless motor reaches a peak torque of 500 mNm at 1000 rpm without a gearbox, achieved from a motor with a square flange of 42 mm. The maximum length of the integrated unit is a mere 70 mm. The high efficiency of the solution is obtained due to Technosoft’s implementation of current and torque vector regulation under a field oriented control method (FOC) that practically transforms the motor into a stepless servo motor, dramatically reducing the current consumption and heat dissipation typical to hybrid steppers.
The standard NEMA17 flange ensures multiple sources of gearheads that are available for fitting to the motor, depending on the requirements of the application.
An intelligent motor can be used in many applications, but it has been developed for medical analysis and dosing machines, pick and place and welding robots, instrumentation and optical equipment, unmanned military vehicles, packaging, bottling and labeling machines.
Intelligent Motion Control Drive
It has also released the iPOS3604 HX-CAN—a closed frame intelligent drive offering a very compact solution for sinusoidal or trapezoidal position, speed and torque control of rotary or linear DC Brushless and open-loop or closed-loop control of 2-phase and 3-phase step motors requiring power up to 144 watts. The supply voltage range is 12 to 36 VDC with a continuous current of 4 A, (10 A peak) and a PWM frequency of 20 KHz.
This high performance servo drive offers high level single or multiple-axis control functions such as master, slave or standalone operations in a small package of only 80 x 55 x 16 mm. Although extremely compact, iPOS3604 HX embeds motion controller, drive and PLC functionality in one unit.
iPOS3604 HX can operate as a CiA402 CANopen drive, or can be programmed to execute complex motion programs directly at drive level, using their built-in motion controller and the high level Technosoft motion language (TML).Thanks to the TML instruction set, the iPOS3604 HX is an intelligent drive, programmable at user’s level and offering position and speed profiles, PVT & PT interpolated, electronic gearing and cam, external reference: analogue or sent via a communication bus.
The configuration, tuning and programming of the iPOS3604 HX-CAN drive is easy with Technosoft’s powerful graphical platform, EasyMotion Studio. System configuration and parameterization are performed by selecting and testing the system structure, motor and sensor types and control mode.
Flexibility and easy implementation make the iPOS3604 BX-CAN drives an ideal solution to fulfilling today’s motion axis control needs, using modern distributed intelligence architecture.
