Motor manufacturers today — especially those making fractional horsepower motors — are challenged to increase the power their products can produce and reduce their size. A straightforward and well understood way to do this uses a manufacturing technique called segmented stator technology, or 'cut core' technology. It's a tedious process that's hard to automate, but it packs double the amount of copper in the stator windings. Although it increases the motor price by 30%, it boosts the torque density by a factor of two or three. Paul Murphy from Moog Components explains the construction and its benefits in this video.

MICROMO announces the addition of a family of linear and rotary piezo motors to its product offering. The simple, cost-effective, robust designs meet the needs of applications from consumer electronics to metrology instrumentation.

Imperial Electric's compact 525-LS direct drive elevator machines replace AC geared machines in 1:1 roped applications. Highly efficient 525-LS machines deliver the advantages of ACPM synchronous "Green" gearless technology and can be installed in a short timeframe. Available in 2000, 2500, and 3000 lb capacities and speeds from 150 to 450 fpm. Learn more.

Even engineers who buy medium voltage AC motors have a compact option now that the SH630 has joined the family. It runs on supply voltages of 2.3 to 13.8 kV, and offers high horsepower — up to 11,000 hp (8.1 MW) — for heavy duty process industry applications. It also has a wide selection of cooling configurations.

Three energy-efficient 20 MW 'Azipod' propulsion units power the world's largest (5,400 passenger) and most spectacular cruise vessel. Electrically driven propellers mounted on steerable pods external to the ship drive the newly launched $1.2 billion Oasis of the Seas. It took 5,000 km (3,125 miles) of cable just to wire everything.

This graphite-commutated version complements a range of 'coreless' DC motors. They feature quick acceleration and great robustness. These differ from standard iron rotor DC motors in that they are equipped with a self-supporting copper coil which is very light and has a low moment of inertia. Control electronics are available.

Designed for smooth operation at low speeds, the frame of this DC motor is made in a square shape that improves commutation and heat dissipation. It also requires less mounting space than round body motors. They operate from solid-state rectified power sources and range from 1.5 to 500 HP (1 to 396 kW).

The Rossi STANDARDFIT AS07 worm gearmotor and ES07 coaxial gearmotor offer the best performance in torque and service on the market. STANDARDFIT requires no modifications to existing machines due to its overall dimensions matching the worldwide standard. This allows the gear reducer to be replaced easily without additional costs.

Are you looking for a DC-motor manufacturer with capabilities to supply customized motors and gear-motors for small and medium production volumes?

DOGA is specialized in design and manufacturing of customized products. The use of our adapted direct drive and geared motors helps our customers to reduce costs and to simplify design.

This German motor manufacturer introduced a servomotor design that is about half the length of standard servomotors. The higher power is achieved using an optimum copper filling factor for the stator windings. The motors will initially be available in three sizes and in five lengths, and come with various encoders and brakes.

This stainless steel protection system for linear drives was designed for industries that deal with sticky and sugary fluids, such as in food manufacturing. The 'Clean Design' with its specially built longitudinal seal protects not only the linear drive, but the associated guides and position sensors. The drive can survive frequent washdowns.

The latest version 3.0 of an energy efficiency estimating tool BE$T may be downloaded. The software analyzes the annual cost and efficiency of existing installed motors. It also suggests the savings that could be achieved by replacing existing motors with (no surprise here) equivalent sized Baldor premium efficiency motors.

A servomotor with an antenna on it — how cool. This Danish manufacturer takes motor integration a step further by including wireless communication modules that eliminate cabling (except for power). No more broken cables or loose connections. With mesh networking, data from any node can reach any other node.

GK Power Technology Ltd. focuses on developing and producing high precision low backlash planetary gearboxes for industrial automation applications. Review our reliable AC servo motors system, mainly used in the automation fields of CNC machine tools, packing and printing machinery, cutting welding equipment, electronic equipment, engineering machinery, and robots.

The 3-phase DC brushless motor from China MS Motor Co.,LTD provides excellent performance. Our products have a good weight/size to power ratio, excellent acceleration performance, long service life, and less acoustic and electrical noise. Review several series of our brushless DC motors.

For several years, articles have discussed an impending shortage in available engineers. Surprise: the number of mechanical engineering graduates in the U.S. has increased 27% in the last six years. What's behind this sizzling new trend? It's because with a somewhat more general field like mechanical engineering, engineers can get involved in a great variety of exciting multidisciplinary technology areas. Included in the list of 'growth' areas are alternative energy, electric vehicles, mechatronics, and biomedical engineering, says this Design News editorial.

When it comes to the pastime of ice fishing there are only two camps — those who swear by it and those who think it's crazy. But then there is the engineer's view. Think ice fishing is cold and boring? Ah, the Wilcraft (an ice fishing car) makes it all fun. It travels on either ice or water, so there's no worry about hitting thin ice. Get it to where you want it, cut some holes, and it turns into a cozy tent where you can be warm and comfortable while fishing inside.

Are Electric Cars an Energy Panacea?

Electric cars may be the environmentalists' dream, but the energy has to come from somewhere. What will be the end result of plugging tens of millions of battery chargers into the national power grid?
