Marathon stainless steel and jet pump motors from AutomationDirect
New Marathon Powerwash SXT washdown duty motors are designed for use in food and beverage processing and other washdown environments. The all stainless steel, totally enclosed motors are available in single and three-phase. C-face with rigid base (footed) and C-face footless mounting options are available. Jet pump motors are commonly used in commercial and industrial water treatment and processing applications to power centrifugal and hydraulic pumps. Marathon jet pump motors are available in single and three-phase, and in TEFC and Open Drip Proof (ODP) designs. The ODP design allows air to circulate through the motor windings for cooling, but prevents drops of liquid from falling into the motor. The increased air flow means lower operating temperatures and increased efficiency when compared to TEFC or TENV motors.
Emergency braking in power outages, long holding power
Miki Pulley's BXW Spring Actuated Electromag-netic Brakes utilize internal compression springs to provide power-off, fail-safe braking. The primary moving part in this robust but simple brake design is the armature plate. When actuated, the brake compression springs push the armature plate into the friction disc when power is disengaged. This feature provides fail-safe braking and allows the brake to maintain position over long periods of time, thus preventing machinery from "coasting" when powered off. Brakes are ideal for small and large applications, including use with servo motors. Additional features: quiet operation, high holding torque, space savings, long service life, stable and reliable braking power, and manual release mechanisms.
First subsea actuator to have advantages of both electro-mechanical and electro-hydraulic systems

Low-profile rotary positioner with high-force torque motor is mountable on 6-axis hexapod
Nanoposition-ing leader PI has expanded its PIMag series of high-dynamics linear and rotary positioning systems with a new high-performance rotation stage. The low-profile (1.1-in.) V-610 is equipped with a high-force 3-phase torque motor with direct incremental encoder for position feedback and closed-loop operation. Direct drive torque motors do not require gears and mechanical components, eliminating friction in the drive train. Despite its compact size, the ironless motor provides a peak torque of 1.2 Nm (10.6 in.-lbf). Ironless motors provide smoother running with better velocity control due to the lack of cogging effects caused by permanent magnets. Can be combined with PI's H-811 hexapod 6DOF parallel positioner, adding unlimited rotation to this compact 6-axis alignment system.
Custom gearmotor lifts up to 10,000-lb boat
A boat lift manufacturer contacted the engineering team at Bodine Electric Co. to assist in the development of a new high load-capacity vertical boat lift. The application demanded that the gearmotor be suitable for long-term use in a harsh waterfront environment, deliver high starting and running torque, positive locking capability when not running, and be powered by the 24-VDC battery/solar cell systems included on the lifts. The gearmotor efficiency also had to be high to permit many lift cycles from the charged batteries.
