Bodine Electric Company Receives Workplace Success Award

Bodine Electric was recently awarded the Workplace Success Award from Iowa’s Department of Education for their efforts in supporting numerous training and workforce preparation programs at Northeast Iowa Community College (NICC).

Bodine Electric Company collaborated with NICC to develop training and education programs aimed specifically at technical jobs that require more education than a high-school diploma, but less than full college degree. According to the company’s Executive Vice President, Jeff Bodine, there is a significant gap in the educational makeup of the Iowa workforce. “Middle-skill jobs such as CNC machinist and industrial maintenance technician represent 56 percent of Iowa’s employment needs, yet only 33 percent of Iowa’s workers have the skills to fill these critical occupations,” he said during the award ceremony.

Bodine worked closely with NICC to bring this idea to life. The company donated equipment, developed and reviewed curriculum, and along with other local employers worked with the program advisory board to ensure graduates would be well positioned for success after graduation. Currently, the company is working with NICC to expand the curriculum to include a non-credit mechatronics specialist certificate.

Not only are more positions available to these students, but they have the opportunity to choose where they would like to start. Bodine’s program allowed NICC students to shadow current employees, tour the plant itself, and apply for internships immediately after graduation. Bodine also sponsored recent graduates from the NICC program with a hands-on 2-week training program. According to Dubuque’s Telegraph Herald, ninety-three percent of recent program participants found employment since graduation.

Iowa Department of Education Director Brad Buck stated that this training effort highlights Bodine’s long-term commitment to the Peosta/Dubuque area. Instead of ‘switching gears’ and moving their plant elsewhere, “Bodine tackled its worker shortage by partnering with local educational institutions to elevate the entire community.”

New DC Motor Speed Control with Dynamic Braking

Bodine Model 0794 PWM Control with Dynamic Braking

Bodine Model 0794 PWM Control with Dynamic Braking

Our new stock control, model 0794, features a Forward-Brake-Reverse (FBR) switch for dynamic braking. The new control is ideal for use in bi-directional applications such as conveyors, packaging machines, screen-printing equipment, food processing applications, medical devices, lab instrumentation and labeling equipment.

Housed in a NEMA 1/IP-20 enclosure, the new model 0794 provides smooth speed control for PMDC gearmotors and motors. Its pulse width modulated (PWM) design provides higher torque and lower motor operating temperatures than typical SCR controls. Filtered DC output to the motor allows cooler operation, longer brush life, lower audible noise, and wider speed range. The type “WPM” control accepts 115 VAC, 50/60 Hz, 1-phase input. Motor power ratings are 7/16 HP (326 Watts) at 90 VDC, or 5/8 HP (466 Watts) at 130 VDC.

The Forward-Brake-Reverse switch allows dynamic braking in applications where the motor needs to be manually and infrequently reversed, or when required as a setup function in an application. Five trim pot adjustments (TORQ limit, MIN and MAX speed, acceleration/deceleration, and IR compensation) eliminate the computer-like programming required in other drives. DIP switches allow the control to be easily calibrated for different motor sizes. Two Diagnostic LEDs on the PC board indicate when power is on and when current output is at limit set by the TORQ pot.

What is Dynamic Braking?

In basic (non-servo) drive applications, motors and gearmotors are expected to coast only a few shaft rotations after being de-energized. If the application requires precise braking, electromechanical brakes and clutches should be used (see The Bodine Handbook, chapter 10, p.7). In less critical applications, dynamic braking techniques can be employed. Dynamic braking is achieved by altering the connections to the motor with or without the aid of an auxiliary power source, depending on the motor type (DC or AC). In either case, the motor acts like a generator and the kinetic energy of the motor and the driven load is used to exert a retarding force to slow the forward rotation of the motor.

Permanent Magnet DC (PMDC) Motors:  Various techniques are used to accomplish dynamic braking in fractional horsepower PMDC motors and gearmotors. One benefit of the permanent magnet (PMDC) motor over a shunt wound DC motor is that in case of a power failure, the PMDC motor’s braking capability is not affected, because its magnetic field (a permanent magnet rather than a coil) is maintained during a power outage. A normally closed relay or similar device across the armature will automatically function in case of a power failure, shorting the armature’s terminals and initiating the braking action. This inherent characteristic is beneficial, for example, in unwind/rewind applications to prevent unwanted spillage of tape or wire.

The nature of the load is often a vital factor in dynamic braking applications. Caution must be exercised in applying motors which are to be dynamically braked or plugged. In such applications, high currents and dynamic mechanical forces are generated during the braking period. For safety reasons, the thermal and structural capabilities of the drive system should not be exceeded. Dynamic braking of high inertia type loads require additional consideration because of the mechanical and thermal strains which can be induced in both the motor and other associated torque transmitting components. While temperature rise is important in the normal operation of a motor, it is even more important in the dynamic braking of the motor. Since the braking torques generated with some schemes are higher than normal running torque, the energy which the motor must dissipate rises correspondingly. Brush life can be expected to decrease when the frequency or duration of dynamic braking is substantial. Special brushes are usually required.

Model 0794: When the FBR switch on model 0794 is set to “stop” (dynamic braking), the armature leads are disconnected from the control and a braking resistor is connected across the armature terminals causing the motor to decelerate. The response time, or time to dynamically brake, is dependent upon the inertia of the armature, the inertia of the load, brake resistor value, initial speed and a number of other factors. The dynamic braking feature can help to improve cycle times, machine set-up time, and overall process efficiency.

New 3-Wire-Reversible AC Fixed Speed Gearmotors

42R6-FX - New Bodine AC Gearmotor, 3-Wire-Reversible

42R6-FX – New Bodine AC Gearmotor

We expanded our popular FX line of parallel shaft gearmotors by adding (9) new AC models. The all-new 42R6-FX combines our new 3-wire reversible 42R frame AC induction motor with our completely redesigned and updated FX gearhead. The new gearmotor provides up to 40% more torque than previous E/F models. New synthetic lubricant allows the FX gearhead to operate at a wider temperature range while at the same time improving overall gearhead performance. Stronger, hardened helical steel gears and new needle bearings provide more torque and 25% longer product life. The 42R-FX achieves these gains in power, performance and flexibility without any change in the gearhead dimensions or mounting configurations.

The 42R6-FX gearmotor is ideal for fixed-speed applications such as medical equipment, packaging machines, conveyor systems, printing equipment, and factory automation applications.


The 42R6-FX is driven by our new 42R6-frame 115 VAC/60 Hz, single-phase 1/4 HP (186 Watts) AC motor, which is 60% more powerful than Bodine’s earlier E/F models. The three-wire winding makes the gearmotor easier to wire and to reverse. The new FX gearhead provides up to 350 lb-in. (40 Nm) continuous torque. Models are available with gear ratios ranging from 5:1 to 300:1 and rated output speeds of 5.7 to 340 RPM. Special order models with 230 VAC 50/60 Hz windings are also available with lead-time and minimum quantities.

Availability: These new stock models are available through Bodine’s extensive distributor network, via direct sales to OEMs, or from the Bodine web site. Stock orders typically ship within 2-3 business days.
