In response to the obsolescence of the Baldor-Reliance fractional horsepower (FHP) gearmotor line, we are excited to announce the addition of (80) new 90V and 180VDC gearmotors that are fully compatible with unfiltered SCR speed controls. The gearmotors feature SCR rated windings that run at 2500 RPM armature speed at 90V or 180VDC respectively. The new stock models can replace 90V or 180VDC gearmotors sold by Baldor, Bison Gear, Leeson, or Grainger.

We offer three new “SCR Rated” parallel shaft series and one right-angle hollow shaft gearmotor series. The type 24A-Z, 33A-WX and 42A-FX parallel shaft gearmotors feature unvented gear housings and all-steel gear trains that are permanently lubricated for maximum life and performance. The type 33A-5L/H hollow shaft gearmotors are available with several shaft kits and a base mount kit that makes them a direct Baldor drop-in.

We also offer unfiltered SCR speed controls: models 0865, 0866, 1865 for most 90V & 180V 24A and 33A “SCR” models [up to 1/5HP]. Our UPM control model 0867 is suitable for our 90VDC 24A and 33A gearmotors.

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.

Tech Tip: What is an “SCR rated” PMDC gearmotor? We define it as a permanent magnet DC gearmotor that is designed to operate with an unfiltered SCR speed control while delivering similar speed and torque performance as a PMDC gearmotor that is designed to be operated from a filtered DC speed control or from a PWM speed control. SCR rated PMDC gearmotors or motors are designed to remain within their safe operating temperature range while delivering full rated torque over the entire speed range (when operated with an unfiltered SCR speed control). This is in contrast to PWM-rated PMDC gearmotors or motors which would need to be operated at reduced torque if they were operated with an unfiltered SCR speed control.
