Velocity controller

Helps minimize motor size

A sensorless velocity controller reportedly boosts the efficiency of open-loop, ironless-core, brushless motor applications. According to reports, the TG2601 vControl minimizes high-current ripple by operating at high frequency. This unit commutates the motor without the need for position sensors. Motors operate as a commutated brushless entity in a velocity-mode with an inner current loop. ThinGap Motor Technologies, www.thingap.com Enter 591

Stepper motors

High resolution capability

The INS20-PF stepper motor series is available for OEM applications for automated equipment. The motors supply up to 200,000 steps per revolution and more than 187 oz-inches of holding torque. Available in NEMA sizes 17 and 23. Units perform in 16 resolution modes. Applications include medical, robotics, semiconductors, packaging, lasers, CNC machines, conveyors, woodworking, and aerospace. Nyden Corp., www.nyden.com Enter 592

Hub motors

110 or 220 inch-lbs torque

XTi Hub Motors(TM) use an integrated, changeable rubber tire and a dc, geared brush motor to drive vehicles like three-wheel electric carts. One 24V and two 12V models are available. The 12V models are available with and without a friction disc, and the 24V version has an internal electric brake. Standard speeds are 76 rpm at 12V, and 156 rpm at 24V. Controllers and throttle systems are also available. Assembled Products Corp. www.assembledproducts.com Enter 593

Unground bearings

Burnished races offer smooth operation

Heim Unibal(R) ball bearings handle high loads and reportedly higher load capacity than caged or split-ring bearings. Manufacturing methods produce races uninterrupted by splits or slots. Bearings are not ground but can be used in place of ground bearings in many applications including wheels, casters, ammunition loaders, door closers, textile machines, power tools, conveyors and pulleys. Bearings are available in plain, flanged OD, and clevis mounted, and in standard and special configurations. RBC Bearings, www.rbcbearings.com Enter 594

CNC controllers

UMAC, QMAC available

The Advantage 810 CNC application family supports high-speed machining, contouring, and 5-axis operations. The operator control panel has five user-definable function keys; embedded, preloaded software; and an autopilot, quick setup tool. A single USB interface cable connects the console and motion controller. Works with existing motors and amplifiers. The Advantage 810 supports dynamic multi-block for path fidelity at any speed.

Machining center

Optional 4th and 5th axes

RoboDrill B Space Saver machining center reportedly offers capabilities of large centers in a compact footprint. RoboDrill performs rigid tapping to 6,000 rpm, peck tapping for deep holes, and high-speed reverse tapping. Its working table has a capacity to 330 lbs. Space Saver's rigidity and milling performance approaches that of a 40-taper machine, the company says. Applications include CNC milling, drilling, boring, deburring, and chamfering.

Closed-loop controller

Handles to 50 gpm

Operators achieve instant remote control using a self-contained, closed-loop controller that offers plug 'n play connection. The controller is available with single or dual controls and is reportedly ideal for applications that require stability when flow, pressure, or temperature changes. This unit can control flows up to 50 gpm and pressures to 3,000 psi. A comparator or smart card is available separately. Source Fluid Power www.sourcefp.com Enter 598

Stainless gas spring

Offers for corrosion resistance

Reportedly offering protection against adverse, corrosive environments, GSSX stainless steel-shafted gas spring also offers longer service life, the company reports. Contaminants are less likely to work their way inside the gas spring tube breaking down seals and causing the spring to fail. Features include a lip seal inside the tube and composite end fittings. Applications include marine and land-based vehicles and equipment. Service Plus Distributors www.spdhardware.com Enter 599

Cast iron wheels

Withstands higher temperatures

V-groove, cast-iron wheels reportedly have very low tractive resistance and high-temperature tolerance. Wheels feature a ball journal bearing for strength. Available in diameters of 3, 4, 5, 6, and 8 inches, cast wheels have load capacities of 450 to 2,000 lbs. Various groove widths are available, as well. Standard finish is a clear shellac.

Linear drive

Rolling-ring bearing assembly

Kinemax linear drives offer variable pitches, making it possible to spool materials of varying diameters on one winding assembly. Linear pitch is set using a control dial on the drive face. The pitch remains constant regardless of motor speed or take-up reel speed. This drive provides up to 6.8 lbs of axial thrust and the maximum pitch of 6.2 mm. Amacoil Inc., www.amacoil.com Enter 601

Conveyor clutch

No rotary air union

The Air Champ(R) straight-bore conveyor clutch can be modified for a variety of sprockets, timing belts, or pulleys. The LSCC-32 is ideal for soft starts in accumulating, chain-driven, live-roller, or in-line conveyor applications, the company reports. The product is activated by air pressure, driving the sprockets attached to the clutch drive flange. Springs keep the clutch disengaged when air is off. The product can be configured for clutch-brake operations. Nexen Group Inc., www.nexengroup.com Enter 602
