HIGH-TORQUE SERVO MOTORS

The MP-Series of brushless servo motors combine high-efficiency and high-torque to create powerful, yet small motors. They are targeted for the packaging industry, for smaller machines. Acceleration is quick because of the torque-to-

inertia ratio. The advantage is it takes less time to move loads. Various motor winding configurations are available, some of which permit the use of smaller, less-expensive drives. Rockwell Automation

MEETING ENERGY NEEDS

Single-phase and three-phase AC motors in NEMA 213T and 215T rolled-steel frame sizes incorporate design advances that result in a more energy-efficient motor. Operating efficiencies meet or exceed those mandated by the Energy Policy Act. Sizes include 7-1/2 and 10 horsepower, with some 5 and 3 horsepower models. Leeson Electric Corp.

SERVO ACTUATORS

AR series of servo actuators combine the servo amplifier, servo driver and controller into one unit. The self-contained electronic gear means positioning data can be set without considering the machine’s reduction gear ratio. With built-in brake control functions, there are four types of actuators. Capacity ranges from 0.4 kW to 2.5 kW. Harmonic Drive Technologies

PUT A BRAKE ON IT

Servo motor brakes, available in eight size groups, fit more than 250 servo motors from 15 servo motor manufacturers.

STOP PACKAGING SHOCK

The Cushion-Comb honeycomb shock-absorbing material is made entirely from paper. Precrushed, the honeycomb cells absorb repeated shock, minimizing "road shock" to products during shipment. This material consistently produces repeatable cushioning characteristics similar to those found in plastic foam, polyethylene, polyurethane and polystyrene. In use, it’s usually oriented and adhered to a sheet of corrugated, both of which can be disposed after use. Pactiv Corp.

AC-POWERED LIFT TRUCK

Line of lift trucks uses AC motors for drive, lift, lower and steering functions. AC power offers speed and acceleration capabilities that surpass DC power. In addition, AC technology offers high torque at low speeds. With regenerative braking, wear on mechanical brakes is considerably reduced. It also returns up to 15 percent energy to the battery. The hydrostatic drive eases movement up and down ramps. Steinbock

ENVIRONMENTALLY FRIENDLY FILL

Hex700 panels have the same compression rates and performance characteristics as one-pound expanded polystyrene. This paper-based, void-fill material does not crumble, but can be recycled with other paper and paperboard products. It’s made of Kraft paper (linerboard) and water-based adhesives. Its vertical cell orientation enables the honeycomb to handle heavy loads without loss of strength. Custom sizes to 60 inches wide by 144 inches long are available for orders exceeding 20,000 board feet. Pactiv Corp

CONNECTIVITY WITHOUT ENCLOSURES

IN THE ZONE

Zoned accumulation conveyors handle heavy, bulky loads. Available in medium- and heavy-duty roller diameters, capacities range from 20 pounds to 5,000 pounds. The medium-size rollers have 1.9-inch diameters, the heavy-duty have 2.5-inch diameters. Widths are to 60 inches depending on load and roller size. When a load enters the conveyor, it is driven to the farthest unoccupied zone. The load depresses the sensor roller at the end of that zone, which disengages a clutch and readies the succeeding zone. This sequence is repeated until all zones are filled. When a load is removed, its sensor roller is released, signaling the accumulation zones to move up. TKF Inc.
