Unique Inverter Duty AC Motors from Groschopp

Sioux Center, IA – Groschopp’s AC motors are inverter duty classified. The inverter duty motor is small and compact, in order to reduce energy consumption. The smallest AC motor offered, the AC65, measures just 2.88 inches square and 5.22 inches in length. This motor series is designed to directly integrate with Groschopp’s standard reducer lines with minimal interface components optimizing both size and cost. Groschopp’s AC motor further reduces energy consumption with its ability to run at varying speeds.

The Groschopp AC motor is utilized best in a long-life, continuous duty, application. It has no common wear parts such as brushes and commutators, so it is highly reliable, featuring long life potential and low maintenance. Since the AC motor maintains speed over a wide range of torque it integrates well with commercial ovens, conveyers, insulation blowers, augers, medical beds, x-ray tubes and other conveyer and continuous motion machines. With customization options for speed control and high heat resistance along with the convenient customization from standard to food-grade grease permits the AC motor to synchronize well with commercial, industrial, and construction applications.

The standard features in a Groschopp AC motor include: rugged ball-bearing construction, high-efficiency stator and rotor tolerances and impregnated windings designed to withstand more than twice the nominal voltage.

The Groschopp AC motor has a superb heat dissipation system. Groschopp’s AC motors have innovative cooling channels in the motor housing to avoid dust and grime build-up that can cause overheating and motor damage. “This special cooling mechanism allows the motor to run at lower speeds without overheating which is vital to an inverter duty motor” comments Tullar “we want our motors to last forever.” To further withstand the heat these motors also have insulation that meets “H” class temperature ratings with the ability to withstand temperatures up to 180 degrees Celsius.

Groschopp offers a single phase, 115 and a 230 volt AC motor and a high power, 230 volt, three phase motor. Groschopp can also custom build a dual voltage AC motor. Having both single and three-phase design options provides multiple cost-effective choices depending on the supply voltage and control requirements. “One of the best features of The AC motor is it’s lack of noise” says Tullar. “This AC motor runs so quietly it will not add any additional noise to your workplace,” this is thanks in part to the motor’s ability to run on low current. (Groschopp motors are UL, CSA, CE and RoHS compliant).

ULT Slotless Direct Drive Frameless Motors

Applimotion’s ULT Series slotless air-core direct drive frameless motors are ideal for new direct-drive applications. New sizes are released weekly covering 60-450mm diameters. The latest slotless versions are optimized for smooth low-speed motion for positioning or precision scanning applications. These motors remain true to the ULT ultra-thin origins with low-profile construction and large through holes.

These motor operate from traditional three-phase brushless DC or AC sinusoidal servo drives. Windings are available for operation from 12-300 VDC.

The cross section profile of these motors is very thin, allowing users to take advantage of a small outside diameter and a large through hole. These direct-drive, low-profile frameless motors also allow designers to reduce overall system height.

Bodine Adds Gearmotors and Motors to Pacesetter™ Product Line

CHICAGO, IL — Bodine Electric Company added over twenty new 230/460 VAC, variable speed, three-phase gearmotors and motors to their Pacesetter™ product line. These new models are ideal for factories where various power supply options are present. They provide a wide range of torque, speed, and horsepower to fit a wide variety of applications such as conveyor systems, packaging machines, and factory automation. These highly efficient, variable speed AC motors can help to reduce power consumption and lower production costs.

The 34R and 42R frame motors are now available with dual voltage windings and inverter duty ratings. When operated with an AC speed control (inverter), these motors have a speed range from 120-3,650 rpm; maximum torque of up to 281 oz-in. (2 Nm) and are rated from 1/4 to 3/8 HP. They can be matched with Bodine’s three most popular gearheads, the type E, F and 5N. The type E and F are both parallel shaft designs, with gear ratios from 5:1 to 300:1; their torque is rated from 25 to 341 lb-in. (up to 39 Nm), and power is rated up to 3/8 HP (280 W). The type 5N right-angle gearhead has gear ratios from 5:1 to 75:1. It provides a torque range between 54 and 116 lb-in. (up to 13 Nm) and up to 3/8 HP (280 W) power. Larger type 48R dual voltage motors and gearmotors are already available up to 3/4 HP (560 W).

All Bodine Pacesetter inverter duty AC motors and gearmotors feature Bodine’s Quintsulation™ 5-stage insulation system, which meets NEMA MG 1-1993, Section IV, Part 31. This insulation protects the motor from potential spikes or corona damage caused by the inverter. Pacesetter gearmotors are UL or CSA recognized for construction, cURus or CSA/UR marked, and in compliance with the Low Voltage Directive “CE”, and RoHS compliant.
