With new standards and demands continually developing across industries, the technologies behind AC gear motors are keeping up to help them increase productivity and save money.
AC Gear Motors: Basic Operating Principles
What are the basic operating principles of AC gear motors? How do they work? Our custom motor manufacturing experts answer these questions and more.
7 Tips for Working with DC & AC Gear Motors
To help ensure that your DC or AC gear motors perform to the best of their abilities, we’ve compiled some handy tips to keep in mind.
Tips for Selecting Your DC or AC Gear Motor
By selecting an AC or DC gear motor based on the application’s requirements, you can ensure it is the perfect one for the job.
Benefits of AC & DC Gear Motors
A gear motor—whether it’s an AC gear motor or DC gear motor—is a small motor that’s designed to work with a gear reducer. The design of DC and AC gear motors makes sizing the gear reducer and motor simpler.
DC & AC Gear Motors: Terminology Overview
Gear motors—like AC and DC gear motors—have two main components in their integral assembly: a speed reducer and motor. The speed reducer is the part that contains the gears. The motor is AC or DC powered. Gear motors are available in a variety of styles and sizes, and knowing related terms can help you determine the type that’s best for your needs. DC and AC Gear Motor Terms Axial movement: The movement at the ends of input and output shafts. Backlash: The output shaft’s rotational movement when the input shaft is stationary. Center distance: The distance between the center of…
AC vs. DC Gear Motors: What’s the Difference, and Which Offers More Gear Motor Advantages?
Ask an engineer to list the differences between AC gear motors and DC gear motors, and you can expect a quick, concise answer: AC motors are generally smaller, less expensive, lighter and more rugged than brushless DC motors. DC motors, on the other hand, are generally considered better for variable speed operations. Their improved speed control makes DC custom motors more expensive to purchase and maintain, generally. Given enough time, the engineer might explain the technical aspects that differentiate these two gear motors. If speaking to a layperson, the engineer would explain that AC stands for alternating current, while DC…
Gearmotors: Understanding Planetary Gears
Also called an epicyclic gear, a planetary gear is a system containing one or more outer (planet) gears that revolve a central (sun) gear. The outer gears are mounted onto a carrier (moveable arm) that rotates in a manner that’s relative to the sun gear. There are two types of planetary gears: simple and compound. The simple gear has one sun with a single ring, a single set of planets and one carrier – one example would be a manual pencil sharpener that uses a crank. Compound gears have a meshed-planet, stepped-planet or multi-stage structure – for example, bicycle gears….
Advantages of the AC Gear Motor
AC gear motors and DC motors each have their own distinct characteristics, applications and benefits. However, when you need to make a choice between the two, you may find the AC gear motor to be far superior. The following is a look at some of its advantages. Size: An AC gear motor is generally smaller and lighter in weight. Cost: DC motors can be more expensive to purchase and maintain. Durability: AC gear motors are more rugged, particularly in wet, hazardous, potentially explosive and corrosive environments. Speed: AC motor speeds are more precise and can control multiple motors, reach speeds…
Selecting a DC Gear Motor: Uses and Design Features
When you need a DC gear motor, it can be hard to know the right one to choose. The next time you find yourself in this situation, refer to this list of common features of DC gear motorsto help you figure out how to best meet the needs of your application. Features of DC Gear Motors Gear materials: Plastic or metal. Motor types: Wound-field, permanent-magnet, brushless, intermittent and continuous duty motors. Brush-type and brushless motors: The brushed motor gains torque from the power supplied to the motor using stationary magnets, commutation and rotating electrical magnets. Brushless motors use a soft…
