AX Control is one of the largest resellers of motors and controllers in Raleigh, NC and beyond. We see a lot of different parts, and do a lot of repairs. After nearly a decade in business, we know a lot about them. So we thought it was time for us to do one of our FAQs covering some of the most asked questions and issues surrounding motors and controls. <\/p>\n\n\n\n\n\n\n\n

Examples of Industrial Motors and Controllers<\/h2>\n\n\n\n

We specialize in industrial motors and controls. The design of industrial motors makes them ideal parts of blowers, machine tools, turbines, movers, or compressors. Motors may offer rotary or linear force. Such devices play a large part in manufacturing control systems include SCADA systems and PLCs (programmable logic controllers.) <\/p>\n\n\n\n

Types of Motors and Controllers<\/h2>\n\n\n\n

There are four basic types of motors and controllers. They include<\/p>\n\n\n\n

Stepper Motors and Controllers<\/h3>\n\n\n\n

Stepper drives and stepper motor controllers modify input power by changing the current source (typically AC) to a pulsed or “stepped” current output. Manufacturing motion control systems often use these devices. They may control position, torque, or motor speed. <\/p>\n\n\n\n

Stepper drives might appear described as step amplifiers or as pulse drives. “Motor indexers” is another name for stepper controllers. <\/p>\n\n\n\n

Servo Motors and Controllers<\/h3>\n\n\n\n
\"Servo

Servo drives and servo motor controllers change the constant or AC input power source into a pulsed output. Servo devices have a varying frequency or pulse duration. <\/p>\n\n\n\n

Manufacturing motion control applications often use servo devices, just as they do stepper devices. Robotics, machine tools, spindle drives, and many other pieces of equipment use servo motors. <\/p>\n\n\n\n

The terms “servo drive” and “servomotor amplifier” are interchangeable. <\/p>\n\n\n\n

AC Devices<\/h3>\n\n\n\n

AC Drives and AC Motor controllers modify input power by adjusting power frequency for output torque and speed regulation. <\/p>\n\n\n\n

These devices often factor into process applications. They offer speed control for pumps, blowers, fans, etc. <\/p>\n\n\n\n

AC Drives are equivalent to variable speed drives, AC inverters, or adjustable frequency drives. <\/p>\n\n\n\n

DC Devices<\/h3>\n\n\n\n

DC devices modify the input power (either constant or alternating current) into a pulsed DC output. This output has a varying frequency. <\/p>\n\n\n\n

DC motors are made up of two distinct parts. One is called a stator. The other is called an armature. <\/p>\n\n\n\n

The stator is stationary. It is built out of magnets and coils of wire. It provides the magnetic field that drives the armature. <\/p>\n\n\n\n

Motors and Controllers: Industrial Applications<\/h2>\n\n\n\n

AC and DC motors are simple. They don’t need controllers or drives like servomotors or steppers, although they may require a motor starter. However, an AC motor drive may come into play when speed control is necessary. Motor drives increase efficiency by setting the speed to meet output requirements. <\/p>\n\n\n\n

When speed doesn’t meet output requirements, issues with outputs can happen.<\/p>\n\n\n\n
