Variable Speed Motor

The DynaMotor from DynaMotors Inc. (Cleveland, OH) is designed to produce more torque than motors of comparable size. For instance, a NEMA 56 frame TEFC DynaMotor generates 11 foot-lb. of torque at 600 rpm — three times that of a comparably sized PWM inverter and AC motor, according to the company.

Servomotor Couplings

The ServoClass coupling line from Zero-Max (Plymouth, MA) has been expanded with three new sizes to handle bore diameters from 0.875 to 1.378" and operating torque from 3.937 to 9,843 in. lb. The lightweight couplings incorporate Type 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members. All have clamp-style hubs with corrosion-resistant socket head cap screws.

Conveyor System Valve

The Series VFD poppet valve for zero pressure accumulation conveyor systems from SMC Corp. of America (Indianapolis) provides a coefficient of volume flow (Cv) of 0.10 with an operating pressure range of 0 to 72 psi to handle large pressure drops found on long conveyor runs. It is designed to be incorporated with a conveyor system’s control logic and sensors, controlling the air pressure used for roller actuation and roller braking to make for smoother product transfer.

Ultra-High-Speed Thermography Reveals Hidden Features of Hot, Fast-Moving Objects

Most of us have seen still images or slow-motion video of fast-moving objects, such as a missile in flight or a humming bird flapping its wings. Both scenarios are possible with high-speed visible image cameras using ultra-short exposure times and triggered strobe lighting. Video images of this sort generally require high frame rates to ensure smooth playback.
