Most automatic controls involve motor control in some way, especially in factory automation. Applications such as pumps, fans, robotics, and conveyors use motors. Whether general-purpose 3-phase ac motors, which are great for simple on/off systems, or the inverter-duty motors specifically designed for operation with variable frequency drives (VFDs), one could say that motors are ubiquitous in nearly ...

New MTR2 series IronHorse® general purpose, rolled-steel motors from AutomationDirect are available in 1-phase and 3-phase versions and offer better performance specifications, improved cosmetic appearance and quieter operation.
General purpose motors have been around for many years. They are the workhorse of almost every industry. An inverter-duty motor is a much newer concept that became necessary as motors began to be driven by VFDs (inverters or AC drives). An inverter duty motor can withstand the higher voltage spikes produced by all VFDs (amplified ... Read More
AC motors are electric motors driven by alternating current (AC). AC motors are widely used in industry, primarily due to their high efficiency, and their ability to produce constant torque up to the rated speed. AC Motor Types The two most widely used types of AC motors are induction motors and synchronous motors. How AC ... Read More
A stepper motor (sometimes called a step motor or stepping motor) is a DC motor with a fixed number of steps that make a full rotation. The motor can be commanded to move to any one of those step locations and hold position without any need for a position sensor – assuming it is properly ... Read More
Efficient use of motors is always important, but there are many other things to consider when specifying an electric motor. Mechanical and environmental considerations are on the list, as is the application and operation. All of these factors are important, but the application is where the selection process should start.
AutomationDirect’s IronHorse line of general purpose three-phase motors now includes the MTRP-series 56HC-frame premium efficiency motors available from 1 hp to 3 hp. The rolled steel motors are available in 1800 and 3600 RPM models and feature 4:1 constant torque and
AutomationDirect has extended their line of Marathon motors. There are 10 New NEMA 182TC or 184TC frame Marathon motors with YxxxA catalog numbers that match frame size, horsepower and are equivalent in dimension, weight and performance to non “A” suffix models they replace. Refer to the motor drawings for any minor differences from the previous models.
Marathon Electric is a company deeply rooted in the act of invention. It has developed new products and explored new technologies since 1913. From humble beginnings, the company began its operations on an island in the Wisconsin River to produce ¼ hp washing machine motors. Today, it manufactures products using next generation power motor technology. ... Read More
The decision to replace existing motors with newer premium efficiency motors can be difficult. And, a common mistake made is thinking that buying any new premium efficiency motor will deliver optimal efficiency. This paper discusses how to determine whether to rewind or replace a motor, and how to find the right motor size for the ... Read More
