In keeping with our Quality Policy and our dedication to Continuous Improvement, Bodine Electric’s manufacturing and engineering teams joined forces in 2013 to identify and source a 3D printing solution that fits our needs.
The creation of physical prototypes of new castings or moldings or any new part has traditionally been a challenge in the machine shop or tool room because some cast features simply cannot be duplicated. Although stereo-lithography (3D printing) has been around for some time it was fairly expensive to create a part, materials were severely limited and the equipment to produce them was in the $100,000 range. Advances in technology have decreased the size and reduced the cost substantially to allow our joint team to specify and purchase a 3D printer by mid-2013.
This machine takes modeling input from SolidWorks and creates 3D models as large as 410 cubic inches (about the displacement of a ‘69 Corvette V-8) with a layer resolution of .0039”. Three materials are available for modeling, PLA which is a thermoplastic aliphatic polyesteris, PVA which is Polyvinyl alcohol, and ABS which is acrylonitrile butadiene styrene, all these are available in a wide assortment of colors.
We began using this new technology in our manufacturing operations to create fixtures for assembly that closely fit our products to facilitate elimination of torque reaction during fastener driving, while incorporating mistake proofing features where applicable and feasible. Then we moved on to the creation of ball bearing installation fixtures and seal expanders for prototypes and new custom gearmotor designs. Other areas of manufacturing productivity improvements were to design and “print” fixtures to directly aid in easing product assembly and in process storage of wound armatures.
From using this new machine initially for simple manufacturing fixtures and tools, our engineering and R&D team now manufacture many new parts for custom-built OEM designs and prototypes. Examples are new motor front- and rear end shields, gear housing covers and motor adaptors. Other parts we “printed” are custom encoder covers, new terminal-box designs, Hall Effect device holders for our brushless DC motors and a new 24A motor shield with IP-44 lead exit capability.The photos in this article show some parts that we manufactured in house, as well as one part that was printed by an outside supplier. This new technology provides our engineering and manufacturing teams with a tool that enhanced speed to market, allows for rapid prototyping and brings new manufacturing processes faster up to speed. Our customers benefit from it with shorter lead-times and greater productivity during the product development process.

Although commutator and brush assemblies may be used in some types of alternating current (AC) gearmotors and motors (series-/universal wound), brushless induction-type designs are by far the most common and most reliable for industrial AC motors and gearmotors that operate from an AC power source or from an AC speed control (adjustable speed drive).
In an AC induction motor or gearmotor, the stator winding sets up a magnetic field which reacts with the current-carrying conductors of the rotor to produce rotational torques. The rotor currents are induced in the rotor conductors by the stator’s changing magnetic field, rather than by means of a commutator and brushes. This induction action is the central operating principle of AC induction motors.
AC power is commercially supplied in both single-phase and three-phase forms. The essential operating characteristics of AC induction motors and gearmotors will vary according to:
1) winding types (split-phase, shaded-pole, three-phase, etc.), and
2) the number of phases, the frequency, and the voltage of the power source.
2.2 POLYPHASE MOTORS (Two or Three Phases)
The production of a rotating magnetic field can be simply illustrated by considering a two-phase motor with two embedded stator windings for establishing the magnetic fields. Read More…

Below information is from our latest Application Note on how to connect and reverse our fixed-speed, 3-wire and 4-wire reversible, AC single-phase gearmotors and motors. We conclude our series of AC application notes with four examples of what types of reversing switches an engineer or technician can use to reverse our stock gearmotors.
How to Wire an Optional Reversing Switch to a 3- or 4-wire AC (PSC) Motor or Gearmotor (115VAC/60Hz Models)
These connection diagrams show how to wire an optional switch to reverse the direction of a 3- or 4-wire Bodine permanent split capacitor (PSC) motor/gearmotor. All the wiring diagrams use variations of a double throw switch, with a center-off position. The purpose of the center-off position is to bring the gearmotor to a complete stop before reversing its direction of rotation. This is necessary to prevent gearing damage. Table 1 (below) shows examples of switch manufacturers, part numbers and specifications recommended for use with Bodine products.
3- Wire-Reversible Bodine AC Motor or Gearmotor
Examples 1 & 2 show how to connect a single- or double-pole switch to our 3-wire, PSC, fixed-speed AC gearmotors or motors.
4-Wire-Reversible Bodine AC Motor or Gearmotor
Examples 3 & 4 show how to connect a three- or four-pole switch to our 4-wire, PSC, fixed-speed AC gearmotors or motors.
If you have any questions about how to connect our stock products, please give our support team a call at 773-478-3515 (Chicago area), or e-mail us at: firstname.lastname@example.org. All our stock gearmotor and motor connection diagrams are available from our web site.

We would like to thank all attendees for joining us at this year’s Distributor Conference in Northeast Iowa. Attendees came from all regions of the U.S. and from as far away as England. Besides the classroom sessions and the hands-on training, this 2-day event concluded with a number of factory tours at our Peosta, IA plant. Bodine’s commitment to producing the highest quality products is proudly demonstrated at every step of the manufacturing process. Hope to see you at our next event.
