Single Phase (Brushed)

Single Phase motors include brushed motors, voice coil motors, electro-magnets, magnetic bearings, and pure inductive loads. Brushed motors are the most common single phase motor. For the purposes of this article we will be discussing permanent magnet brushed DC servo motors. Construction The brushed DC motor is the simplest and most common type of motor.

Three Phase Brushless Servo Motors

Scope Brushless servo motors include a wide range of motor types including both permanent magnet brushless DC motors and permanent magnet brushless AC motors. They can also be designed for rotary or linear motion. Regardless of the different types, some things they have in common: they use permanent magnets and they are three phase motors. Three Phase Brushless Servo Motors

Inductive Load

Inductive loads are often used in experimenting with magnetic fields or with magnetic manipulation that can’t be categorized as traditional motors. Advantage A servo drive doesn’t distinguish between an inductive load or a traditional motor – the drive will still close the current loop and maintain the commanded current ADVANCED Motion Controls’ Capabilities All off-the-shelf Inductive Load

Linear Motor

  When someone says “motor,” the image that comes to mind for most people is usually something that spins. However, motors can take different forms, such as linear motors. The linear motor was invented in the late 1940s by Dr. Eric Laithwaite of Manchester University. They started off as low acceleration devices, but in modern Linear Motor

Linear Actuator

A linear actuator is an actuator that creates motion in a straight line. Typically a rotary motor is used as the source of actuation in conjunction with a lead or ball screw to create the linear motion. The motors can be either brushed or brushless. Often a feedback device is built into the actuator to Linear Actuator

Direct Drive

Direct Drive means the motor is directly coupled to the load with no mechanical gearing. Linear motors are the most common direct drive motors. Rotary motors can also be set up as a direct drive. Benefit Direct Drive eliminates backlash and can offer faster speed and responsiveness because of reduced friction and no gear reduction; Direct Drive

AC Induction with Feedback (CLV)

AC Induction motors don’t use permanent magnets on the rotor. Instead the magnetic field is induced in the rotor by the magnetic field in the stator.     Benefits AC Induction motors tend to be less expensive than permanent magnet motors for the same power Closed Loop Vector control provides similar performance to permanent magnet AC Induction with Feedback (CLV)


Stepper motors convert input pulses into precisely defined increment “steps”. Each step moves the motor shaft through a fixed angle, with a specific number of steps completing a full rotation. The actual angular rotation of the shaft is directly related to the number of pulses introduced. The position of the load can be accurately determined Stepper

Magnetic Bearing

Magnetic bearings use actively controlled electromagnets to suspend the load. Magnetic bearings are used in high speed and high temperature applications where standard bearings would fail or when ultra low friction is required. Benefit Magnetic bearing applications have a high current loop bandwidth requirement; a tightly tuned servo drive current loop is important ADVANCED Motion Magnetic Bearing

Pancake Motors

Pancake motors are wide and flat, exhibit quick acceleration and deceleration, and have a high pole pair count. They can be either brushed or brushless. These motors are often favored for their precision and rapid start-stop capabilities. They’re also useful when the axial space is limited and application needs a short motor. To be clear, there is no Pancake Motors
