If you're looking for some new tactics to pack more power into your next design, don't bother with Jedi mind tricks. Instead, take a look at some of the latest products featured here to make your next project a star.
Heavy-duty brakes fortify wind turbines
Emergency braking requirements of today's wind turbines under maximum conditions can be compared to those of a 40-ton mining truck driving down a 25% grade at 87 miles per hour with a cliff ¼ mile ahead. To meet these demands, ERS Series electrically released, spring-engaged brakes serve as pitch brakes for wind turbines that require both static holding power and the ability to withstand high inertia emergency stops. The11.3-lb ERS68 has been tested to more than 20,000 fully loaded dynamic stops, offering 100 ft-lb of static torque with a maximum of 2,000 rpm and a brake release time of 0.2 sec.

Step motors pack power into compact package
The 4418 series of NEMA 17 stepper motors provides up to 35% more torque compared to motors of similar dimensions. Motors are available in three different stack lengths, starting with the nimble 4418S at 1.17-in. thickness and the powerful 4418M measuring 1.58 in. Depending on stack length, motors can produce up to 68 oz-in. holding torque. Performance may be customized at no extra cost; various bipolar and unipolar windings are available. Mechanical customizations such as shafts and wiring harnesses may also be added. Motors are suitable in applications where size is a factor and load capacities are critical to precision operation, such as in medical, printing, imaging, optical, and robotics.
High-torque tooth clutch withstands washdown
5H Series tooth clutches deliver fast, no-slip engagement for washdown applications where high torque is required. Clutches offer a positive, single-position tooth interface for synchronized engagement and feature a torque range of 500 to 12,000 in.-lb, with instant torque at engagement up to 7,100 in.-lb. The nickel-plated exterior and rotary seal meet NEMA 1.26.5 protection standards. Clutches are compatible with timing belt sprockets, chain sprockets, belt pulleys, or couplings for use in a range of applications; they can be flange or pilot mounted and are controlled with a 3-way, solenoid, pneumatic valve. Optional solid-lube and/or stainless steel bearings are available.

Planetary gearheads move large loads with ease
XTRUE True Planetary Gearheads, available in 40, 60, 80, 120, and 160 mm frame sizes, are engineered to move large loads easily and quietly with planetary gearing through improved load capacity and lower backlash. They deliver precise 13 arc-min operation, with torque capacity to 876 Nm and ratios from 3:1 to 100:1. RoHS-compliant gearheads may be mounted to any motor in three easy steps: Simply align, mount, and tighten.
Gearmotors offer high torque, Von Weise compatibility
VWDIR104 ac gearmotors (Von Weise drop-in replacement) are available with either 1/10 or 1/15 hp, 115/230 V, and 60/50 Hz permanent split capacitor electric motors. Compact, integral gear reducers feature hardened steel helical and spur gearing for efficiency and durability, with ratios from 108:1 to 266:1. Corresponding fixed output speeds are from 15 to 6 rpm, with continuous torque from 340 to 500 in.-lb. These parallel shaft gearmotors, available in four standard models, feature built-in face mounting and are suitable for high torque industrial and agricultural applications, as in foodservice, office, medical, and conveying equipment.
