By knowing the different types of gears used in AC and DC gear motors, you can have a better idea about the best kind to use in your application.
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.
AC & DC Gear Motor Lubrication Best Practices
The life of a lubricant in AC or DC gear motors is directly related to its temperature. Consider the following tips to keep your machinery running at an optimal level.
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 & DC Gear Motor Efficiency Considerations
Even though it’s critically important, one of the most misunderstood aspects of gear motors is energy efficiency. While performance is an essential consideration when it comes to AC gear motors and DC gear motors, it’s just as important to look at the efficiency of a motor’s design. General Design Many aspects of a gear motor’s design affect its efficiency. Such aspects include the motor’s weight, size, heat losses and heat dissipation capabilities. The gearbox itself is can be a major contributor to power loss and drop in efficiency. Energy Use It’s common to find information about a DC or AC…
China Sourcing of World Class Motor Components: BLDC Motors & More
Manufacturers who build DC gear motors, BLDC motors and other components often look to China to source components like brushes, magnets, and wound coils to keep costs low and maintain a competitive edge. While China offers attractive benefits in regards to sourcing, it’s not without risks when it comes to the engineering of a component. Outsourcing Approaches There are several ways companies can source their BLDC motor and DC gear motor components: Direct approach: When a company wishes to work directly with a Chinese factory, it must find the right factory, negotiate a price, and supervise the production for quality…
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 DC motors. DC motors, on the other hand, are generally considered better for variable speed operations. Their improved speed control makes DC motors more expensive to purchase and maintain, generally. Given enough time, the engineer might go on to explain the technical aspects that differentiate these two gear motors. If speaking to a layperson, the engineer would begin by explaining that AC stands for alternating…
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…
