Ethernet Controller

Galil Motion Control (Rocklin, CA) released the DMC-40x0 Ethernet/RS232 controller family as part of the Accelera line, coming in 1- to 8-axis formats. Accepting encoder input frequencies up to 22 MHz and providing servo update rates up to 32 kHz, the line can complete program instructions in 40 microseconds. The device operates in a standalone configuration or can be interfaced with a PC via the Ethernet 10/100Base-T or RS232 ports. Memory is up to 510 symbolic variables, 16,000 array elements in 30 arrays, and application program space up to 2,000 lines × 80 characters. Mode of motion capability includes: point-to-point positioning, position tracking, jogging, linear and circular interpolation, contouring, electronic gearing, and ECAM. Other features include isolated I/O, eight uncommitted analog inputs and outputs, and PID compensation.

DC Gearmotor

Midwest Motion Products (Watertown, MN) released the Model No. MMP-S28-400A GP81-046 BR-015 DC gearmotor. The device accepts any 24 V DC source. The gearmotor is reversible; the output is rated for 61 Nm continuous torque at 43 rpm and 100 Nm peak. Motor windings for 36, 48, 60, and 90 V are available. The integrally mounted fail-safe brake requires 24 V DC power and features a holding torque of 15 in-lbs. Mounting is accomplished with four “face mount” M-6 threaded holds, equally spaced on a 65 mm B.C. diameter. Dimensions are 3.2 (max diameter) × 13.3" long, and the unit has a keyed output shaft diameter of 19 × 49 mm long.

Servo Drive System

YET US (Manchester, NH) introduced the XtraDrive® servo system, configured for compatibility with all brushless servo motor technologies. The unit features patented non-linear control technology (NCT) for performance and stability; NCT technology allows for zero settling time, and augments non-linear gain control and system productivity. The control structure accommodates changing load requirements, and features an integrated amplifier with an embedded 1.5 axis controller. The system operates as a standalone unit or can be driven by an external PLC or multi-axis controller for step and directional input, analog velocity, or torque control and networking capability. Options include extended I/O, Devicenet, SERCOS, MACRO, and Profibus.

Angle Torque Motors

H2W Technologies, Inc. (Valencia, CA) released limited angle torque motors (“torquers”) that are single phase, brushless, low profile motors, vacuum compatible to 10^5 torr. Options include kit motors and housed motors. A linear servo amplifier and plug-and-play systems are available. Standard/custom designs include miniature 1.4 Ncm continuous, torque 5.2 Ncm peak torque (2 oz-in, 6 oz-in motors) and 706 Ncm continuous torque 2,118 5.2 Ncm peak (1,000 oz-in continuous torque, 3,000 oz-in peak) motors. Two series are available; the MR series feature a toroidally wound iron core stator with 2, 4, or 6 pole permanent magnet rotors, and provides angular excursions to 180°. The series is available in standard and low profile versions.
