How to select an ac motor: A motion engineer’s guide

August 22, 2012 By Miles Budimir Leave a Comment

A gearmotor can be simply a motor with a simple gear attached or as complex as this unit from Nord Gear incorporating bevel gears with a 90-degree hollow-shaft output.

AC motors are among the simplest of motors amid the common choices for motion control systems. There are a few basic criteria for selecting an AC motor. These involve common variables such as the operating speed and load torque, in addition to the power supply voltage and frequency. First of all, calculate the operating speed. […]

What are Transducers for Motion Applications? Technical Summary

October 7, 2011 By Motion Control Tips Editor Leave a Comment

A transducer is essentially a device that converts some form of energy into another form. Common types of transducers used in industrial applications can include sensors used to measure temperature, pressure, force, strain, liquid levels and flow rates, and electrical conductivity among others. In motion control applications, transducers can refer to any one of a […]

What are gears for power transmission? Technical summary for design engineers

October 7, 2011 By Lisa Eitel Leave a Comment

Updated February 2020  || The function of a gear is to mesh with other gears to transmit altered torque and rotation. In fact, gearing can change the speed, torque and direction of motion from a drive source. Geometry & general gear design When two gears with an unequal number of teeth engage, the mechanical advantage […]

What are Motion Control Networks? Technical Summary

October 7, 2011 By Motion Control Tips Editor Leave a Comment

Multi-axis motion control typically uses event-based synchronization. This level of synchronization is defined as scheduled, absolute hard delivery of time-critical cyclic data across the network. Delivery variability must be less than 1 µs, which is also known as jitter. While a number of networks exist for “motion control,” it is important to define the time […]

What is linear motion design engineering? Technical summary

October 7, 2011 By Motion Control Tips Editor Leave a Comment

servo-belt-linear-actuator

Linear motion is an area of motion control encompassing several technologies including linear motors, linear actuators, and linear rolling guides and bearings, among others. Linear motors — an accurate option Traditional linear motors are basically a permanent magnet rotary motor rolled out and laid flat. It’s as if the stator and rotor were cut along […]

What is a motor drive? Summary for design engineers

October 7, 2011 By Motion Control Tips Editor Leave a Comment

Some drives are wholly incorporated into the controller, so that the profile generation takes place in the controller as well as the torque command for the motor. On the other hand, a drive can also refer to the specific power electronic circuitry needed to drive the motor. Electric motors that drive industrial machines need some […]

What are Retaining Rings? Summary for Motion Engineers

October 7, 2011 By Motion Control Tips Editor Leave a Comment

Retaining rings are fasteners that hold together components on a shaft when installed in a groove. There are three main types of retaining rings; tapered section, constant section and spiral. Tapered section rings are characterized by their decreasing thickness from the center of the ring out to the ends. These rings can be mounted either […]

What are servomotors and integrated servomotors? Summary for design engineers

October 7, 2011 By Motion Control Tips Editor 1 Comment

Updated May 2018 by Lisa Eitel || Nailing down the features of a servomotor is a tricky exercise, but the hallmark of any servomotor is the presence of feedback and closed-loop control. Servomotors provide precise control of torque, speed or position using closed-loop feedback. They can also operate at zero speed while maintaining enough torque to maintain a […]

What are Flexible Couplings? Summary for Motion Engineers

October 7, 2011 By Motion Control Tips Editor Leave a Comment

Couplings join together two shafts as a way of transmitting power from one to the other. It is part of the drivetrain which may include other power transmission components such as lead screws or ball screws, gearboxes, belts and pulleys or chains. There are two fundamental types of couplings; rigid and flexible. Rigid couplings are […]

What is a Servo Controller? Summary for Motion Engineers

October 7, 2011 By Motion Control Tips Editor Leave a Comment

More specific types of controllers, such as servo controllers, are used to control servomotors. When dealing with servo systems, it’s important to note that definitions for servomotor, servo system, and servo controllers can differ widely throughout industry. When selecting a servo system for an application, it’s best to ask suppliers what exactly their offerings entail. […]
