Motor Encoder Overview

An encoder is a rotating device which transmits a set number of electronic pulses for each rotation of its shaft. They used to often be seen in industrial settings mounted to the back of DC motors and coupled to the motor’s shaft with a coupling. Sep 06,  · By itself, a DC motor can’t be controlled like a servo motor or a stepper motor. But add an encoder, and you unlock the full potential of the DC motor. Using this approach, you can harness the simplicity, even torque, and lightweight profile of a DC motor for your controlled application. In this tutorial, you’ll learn how to control a motor with an attached magnetic encoder using the PID algorithm.

Encoders turn mechanical motion into an electrical signal that is used by the control system to monitor specific parameters of the application and make adjustments if necessary to maintain the machine operating js desired.

The parameters monitored are determined by enclder type of application and can include os, distance, RPM, position among others. Applications that utilize encoders or other sensors to control specific parameters are often referred to as closed-loop feedback or closed-loop control systems.

The type of motor encoder used is dependent upon a number of factors, particularly motor type, the application requiring closed-loop feedback, and the mounting configuration required. When selecting components for a closed loop control system, the motor encoder choice is first determined by the type of motor chosen in the application. The most common motor types are:. AC induction motors are popular choices for general automation ddc control systems as they are economical encodfr rugged.

Motor encoders are used for more precise speed control in applications using AC motors, and often times need to have more what is a dc motor encoder IP, shock and vibration parameters. Servo motors encoders permanent magnet motor encoders offer closed loop feedback control systems to applications that require higher precision and accuracy, and are not as robust as AC induction motors. The motor encoder used on servo motors can be modular, incremental or absolute depending on the level of resolution and accuracy required.

Stepper motors are cost effective, what is a dc motor encoder, and are typically used in open-loop wwhat. In systems using stepper motors where speed control is required, an incremental motor encoder is often mounted to this motor and will allow what are alms in the bible stepper motor system to achieve closed loop feedback.

Stepper motor encoders can also be used in some applications to allow for improved control of stepper motors by providing precision feedback of the location of the motor shaft in relation to the step angle. DC motor encoders are used for speed control feedback in DC motors where an armature or rotor with wound wires rotates inside a magnetic field created by a stator. The DC motor encoder provides a mechanism to measure the speed of dx rotor and provide closed loop feedback to the drive for precise speed control.

The next factor impacting motor encoder selection is the mounting option, and the most common options are:. The application in which the motor encoder is being utilized will determine the motor encoder technology that needs to be used. The two broad types of motor encoder technologies available are:.

Motor Encoder Mounting Options The next factor impacting motor encoder selection is the mounting option, and the most common options are: Shafted Motor Encoders: Uses a coupling method to connect the motor encoder shaft to the motor shaft. This method is what is the difference between screening and assessment to install and required no shaft alignment, but proper care must be taken to provide electrical isolation.

Bearingless Motor Encoders: Also known as ring mount, this mounting option is motog of a sensor assembly in the form of a ring that is mounted on the motor face, and a magnetic wheel which is mounted on the motor shaft. This type of motor encoder mounting configuration is mostly found in heavy duty applications like paper, steel and cranes.

How to Specify A Motor Encoder

By itself, a DC motor can’t be controlled like a servo motor or a stepper motor. But add an encoder, and you unlock the full potential of the DC motor. Using this approach, you can harness the simplicity, even torque, and lightweight profile of a DC motor for your controlled application. A non-quadrature incremental encoder provides a single pulse to the controller for every incremental motion of the motor shaft. As the previous answer makes clear, this position feedback can be interpreted to infer velocity, acceleration, and possibly jerk (although three derivatives of a sensed value are "spikey" in most applications). Mar 12,  · A DC motor with an encoder is the most common type that can be found in the market. In most cases, it is a generic DC motor with a magnetic type encoder attached to its backside and on the front side, there may or may not be a gear assembly that reduces the RPM and increases the torque.
