The Flexbloc right angle worm gear speed reducers feature the Unicase® housing design and modular construction to suit specific requirements. The speed reducer stops oil leaks and lower operational noise due to its Unicase one-piece housing. This design eliminates bolt-on covers and split casting, to encompass all gearing within a single piece. Additionally, the aluminum alloy housing is corrosion resistant, never requires painting and offers improved heat dissipation for cooler operations and extended gear life. An array of bolt-on components can be easily configured to meet specific application requirements.

Ruland has expanded its rigid coupling line to include smaller bore sizes. One- and two-piece rigid couplings are now offered with bores as small as 1/8" to support the increased use of rigid couplings in motion control applications. Ruland rigid couplings feature precision-honed bores for tight tolerance and precise alignment of the shafts to be connected. Screws have the special Nypatch treatment to prevent loosening when vibration is present in the system. Two-piece style rigid couplings also feature opposing screws for dynamic balancing and thus support higher speeds. The two-piece design allows for easy disassembly and maintenance without removing other shaft components.

Maxon's DEC 50/5 is a compact, digital, velocity controller designed for controlling brushless motors up to 250 watts equipped with hall sensors. The controller has a speed range of 1,000 to 60,000 rpm for 2-pole motors. Requiring a supply voltage of 12 to 50 VDC, the controller can deliver 95% of the supply voltage to the motor at 5 A continuous current or 10 A peak current. Velocity and torque can be controlled via a O to 5 V signal or via external potentiometers. Enable, direction and stop inputs may be activated via external switches. There is also a ready output as well as speed and current monitor outputs.

The Portescap 20M024 Can Stack Step Motors are available with unipolar or bipolar winding construction. Bipolar windings provide up to 1.6 oz-in of holding torque for high torque in a small package, allowing engineers to reduce their package size with a small diameter motor. Windings can be optimized to specific application requirements, with 1.25 watts of input power per winding. The Can Stack Steppers provide a 15 degree step angle and are ideal for a number of medical equipment applications, including analyzers, pipettes and scanners. Their small diameter also makes them a good choice of HVAC and office automation applications. Sintered bronze sleeve bearings are standard; ball bearings are available as an option.

Specifically engineered to satisfy the full constant or variable torque demands of virtually any industrial process applications, the new VLT5000 series drives are available in 125-500 HP (380-500 VAC) and 40-350 HP (525-690VAC). Also available in the new sizes is the FLUX version of the VLT 5000 series, which provides servo-like performance using standard asynchronous AC motors. For variable torque applications, VLT 4000 VT series dedicated variable torque drives are now available in 100-400HP (525-600 VAC). These drives are available with three distinct enclosures.

Danfoss Drives

Vacuum-rated, laboratory-grade servo and stepper motors are designed to survive pressures as low as 10-7 Torr, and are temperature-rated at 130°C internal and 105°C for the case. They meet the specialized vacuum process needs of the observatory industry, particularly in regard to telescope applications. They are also well suited to laboratory applications such as space based optical systems, semiconductor manufacturing chambers and electron beam equipment. Laboratory-grade vacuum motors are available in 11 standard frame sizes, and are a solution to all common vacuum chamber/motor design problems, including outgassing, cooling, air leakage, and corona effects.

Empire Magnetics

The Valuline family of NEMA 23 servomotors is now available in a 4-inch long version to complement the existing 2-inch and 3-inch versions. The 4" versions produces over 50% more torque than the 3" model. Valuline servomotors are now available in 72 W, 132 W and 300 W power levels, with rated speed to 3000 rpm and maximum speed to 5000 rpm. They offer extremely quiet operation and low speed smoothness, making them an effective solution in medical, laboratory, semiconductor, instrumentation and light industrial applications. The servomotors produce constant torque across an entire range of speeds.

The drum motor, also referred to as a motorized pulley, is a highly efficient conveyor drive system where the motor, transmission and bearings are totally enclosed within drum shell. Power from the motor is transmitted through the gearbox which is coupled to a geared rim fixed to the drum and housing. Mounted with just two brackets, there is no need for multiple parts. Installation is quick and easy requiring less than half the time needed to install external drives. The drum motor requires no external component maintenance.
