90Vdc to 180Vdc SCR Rated PMDC Gearmotors

To provide greater flexibility and compatibility with unfiltered SCR controls, Bodine Electric Company now offers a new selection of 90Vdc and 180Vdc gearmotors with a rated maximum armature speed of 2500 rpm. The initial product launch includes 70 standard/stock models with four of Bodine's most popular gearhead designs.

These gearmotors are designed for "hybrid" applications that neither match the 90Vdc, 1725 rpm industry standard for operation with unfiltered speed controls, nor Bodine's typical voltage and rpm for filtered 130Vdc speed control operation. These new stock models from Bodine can replace 90Vdc or 180Vdc gearmotors sold by Baldor, Bison Gear, Leeson, or Grainger.

Bodine SCR rated PMDC gearmotors provide high starting torque, adjustable speed and predictable speed/torque characteristics. All feature Class F TENV insulation. The Bodine type 24A-Z parallel shaft gearmotor features unvented gearhousing and all-steel gear trains that are permanently lubricated for maximum life and performance. It delivers up to 120 lb-in. rated torque. Speed ranges from 14-417 rpm, depending on the gear ratio.

The type 33A-WX parallel shaft gearmotor is constructed with all steel helical gears that meet or exceed AGMA 9 standards for maximum life and quiet operation. It delivers up to 205 lb-in. rated torque, with speeds from 8.0 to 658 rpm, depending on the gear ratio. The type 42A-FX is the largest of the three parallel shaft gearmotors.

Like the type 33A-WX it features hardened steel gearing for quietness and high output. It delivers up to 350 lb-in. rated torque, and speeds from 8.3-500 rpm. The type 33A-5L/H hollow shaft gearmotor connects directly to the driven load and features versatile, universal mounting options. It delivers up to 89 lb-in. rated torque, with speeds from 33 to 500 rpm, depending on the gear ratio.

Availability

The SCR rated gearmotors and their corresponding controls and accessory kits are available through Bodine's extensive distributor network or from the Bodine web site. Custom designs are available to qualified OEMs. Typical OEM modifications include factory installed encoders or brakes, custom wire harnesses, and application-specific mounting and shaft details.
