Senior ME Design Team wins Purdue Mallot Award for “P.E.T.”

Senior ME Design Team wins Purdue Mallot Award for “P.E.T.”

We want to congratulate the “Purdue Prop Pullers” for their success with their Fall 2013 senior design project! P.E.T. is a portable electric tow-bar for a small plane. The purpose of this device is to enable the pilot to pull his/her plane short distances around a hangar with minimal effort. The team’s objective was to

Advantages and Disadvantages of Planetary Gearmotors

Advantages and Disadvantages of Planetary Gearmotors

We design all our standard parallel shaft (helical or helical/spur) and right angle (worm or helical/worm) gearboxes in-house, and all gearheads are manufactured and assembled in our main factory in Iowa. Occasionally, we’ll receive a request to mate one of our standard AC, DC or BLDC motors to a planetary gearhead. To identify the best gearmotor option for our customer’s

New High-Torque PMDC Gearmotors 12/24V or 90/130 VDC

New High-Torque PMDC Gearmotors 12/24V or 90/130 VDC

The new 42A5-FX is a completely redesigned permanent magnet DC (PMDC) parallel shaft gearmotor that provides up to 40% more torque than previous E/F models. Forty (40) new stock models are offered with either 12/24VDC or 90/130 VDC rated motor windings. New synthetic lubricant allows the FX gearhead to operate at a wider temperature range

Selecting DC Motor Speed Controls for PMDC Gearmotors

Selecting DC Motor Speed Controls for PMDC Gearmotors

Basic DC motor speed controls accomplish the conversion of AC power to DC with varying degrees of DC voltage “purity.” For proper control selection you’ll need to identify which performance criteria are important to your application. We’ll review how different speed controls affect the quality of DC output and consequently, the performance of your DC

Low-Voltage DC Motor Speed Controls (12 & 24V) for PMDC Gearmotors and Motors

Low-Voltage DC Motor Speed Controls (12 & 24V) for PMDC Gearmotors and Motors

Bodine Electric Company developed four new stock models to provide simple and reliable speed control for low-voltage 12 or 24V PMDC gearmotor and motor applications (up to 1/3 HP / 250 Watts). The controls utilize pulse width modulation (PWM) technology to insure quiet operation, low operating temperature and optimal brush life. The controls feature five trim pots to

Design Tips for Gearmotor Applications

Design Tips for Gearmotor Applications

To select the best gearmotor for an application, one must go into more detail than just selecting the best suitable output speed and torque. Here are five criteria you should consider. 1. Gearmotor Mounting Orientation Gearmotors are typically designed to be mounted with the gearbox level with the motor, and with the drive shaft in

Selecting Fractional Horsepower (FHP) Gearmotors for Long-Life Applications

Buyers should first decide what kind of operating life is needed. If durability is not an issue, or if the duty is so intermittent that even a short-life (“throw-away”) motor will translate into years of operation, then you’ll want to go with the best price. But if product quality and reputation depends on reliability and

Measuring Armature Circuit Resistance in a PMDC Motor

Measuring Armature Circuit Resistance in a PMDC Motor

Application Notes & Gearmotor Tips: When a permanent magnet DC (PMDC) motor fails to operate properly, or fails to run at all, one sensible troubleshooting step is to measure the winding resistance to determine if there’s an open circuit or a short circuit, either between turns of the same winding, between two windings in the

What does IR Compensation mean, and what is it used for?

What does IR Compensation mean, and what is it used for?

The IR compensation method is used to provide the speed regulation in our DC motor speed controls. When the load of a PMDC motor increases, the amount of current that the motor draws also increases. Per the performance characteristics of permanent magnet DC (PMDC) motors, an increase in load will cause a decrease in speed, because
