Low-Voltage, Right-Angle Brushless DC Gearmotor Combines Four Drive Components in One Compact Package

Low-Voltage, Right-Angle Brushless DC Gearmotor Combines Four Drive Components in One Compact Package

The new type 34B4/FV-5N gearmotors combine Bodine’s 34B brushless DC motor with a compact and cost competitive right-angle gearhead, a built-in PWM speed control, and an optical encoder. Together, they create a high-performance drive package that radically simplifies design, wiring, and assembly. The 24 VDC 34B/FV-5N gearmotors are ideal for a wide range of low-voltage

Introduction to Brushless DC (EC) Motor and Gearmotor Technology

Introduction to Brushless DC (EC) Motor and Gearmotor Technology

Brushless DC Gearmotors and Motors In Section 3.1 of the Bodine Electric Handbook we discuss how motor action is achieved in a conventional permanent magnet DC (PMDC) motor. A segmented commutator rotating within a stationary magnetic field causes mechanical switching of the armature current. In a brushless DC (BLDC) gearmotor or motor, the magnetic field

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

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

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
