New Industrial SR Motor Control System

Striatech has developed a 1.75 hp (1.3 Kw) switched reluctance (SR) motor and dedicated control combination for a
wide range of industrial and commercial applications. The
cost-effective SR motor has no magnets with a programmable control algorithm that allows the user to optimize the
SR motor performance for many applications.
Peak motor torque ranges from 21.9 Nm (193 lb-in) at 600
rpm to 16.8 Nm (149 lb-in) at 3,000 rpm. Motor frame size
reaches almost 8 inches in diameter with an axial length of
9.27 inches. Smaller SR models can reach shaft speeds approaching 100,000 rpm.
The control processes real time monitoring of rotor shaft position. It constantly adjusts motor current to
save up to 50 percent input power. The control uses a USB computer interface.

Applied Motion Products Partners with Heidenhain to Incorporate Renco Encoder in StepSERVO
Integrated Motors
Heidenhain Corp. is partnering with Applied Motion Products, Inc. in the development of their StepSERVO integrated motors for high performance motion control applications. Utilizing's Heidenhain's
Renco brand RCML 15 rotary encoder inside, StepSERVO offers the next evolution in step motor technology, combining the high torque capabilities of step motors with the closed loop dynamic control of
servo systems.

The result is a motor-and-drive solution that operates more quietly and efficiently, while providing greater torque and higher acceleration rates than traditional step motor systems. To develop this system for
use by machine builders, Applied Motion started with a proven integrated motor design, added closedloop servo firmware and Renco's high-resolution incremental encoder to create StepSERVO.
"The Renco encoder is compact, and its thinness allows us to minimize the length of our integrated motor and its relatively small OD allows it to fit inside a NEMA 17 integrated motor," said Applied Motion's
CTO Jeff Kordik. "Also, it is easy to mount, the connector is easy to work with and it delivers 20,000
counts per rev (5,000 lines), which is important to a 50-pole sine commutated servo system."
Kordik further explains that the StepSERVO motor's increase in torque and acceleration leads to greater
throughput for the user, especially where repeated indexing or start-stop motion is required. It is well
suited for applications such as packaging and labeling, automated test and measurement, automated assembly and life sciences, among others.
Heidenhain's Renco brand RCML 15 incremental rotary encoder is well known for its particularly low
profile with a height of 8.9 mm, still offering performance potential of modern rotary encoders, and
particularly useful in applications with limited space and installation conditions. Its performance includes
providing a resolution of 5,000 signals per revolution, commutation signals U, V and W, and an operating
temperature range of -30°C to 100°C. It also features a patented slide lock mechanism for simple, selfcentering mounting

TI Collaborates with Heidenhain to Incorporate EnDat Interface in Industrial Drive Control
System-on-Chip (SoC)

Heidenhain Corp. will be working with Texas Instruments (TI) in the development of the semiconductor industry's first microcontroller (MCU) utilizing the Heidenhain EnDat 2.2 interface as an option. TI's
C2000 MCU industrial drive control System-on-Chip (SoC) delivers a complete solution with a direct connection for industrial motor and servo drives, supporting both analog and digital position sensors.
When combined with TI's DesignDRIVE Position Manager, this new solution eliminates the complexities
of position sensor management in the industrial drive development cycle, saving ancillary components,
