High Temperature Stepper Motor Frame size selection

Generally speaking, high temperature resistant motors are defined by their insulation class. The field of stepper motors usually involves six insulation classes.


High temp stepper motors have special requirements for materials due to their use in high temperature situations, including enameled wire, skeleton, magnets, bearings, grease, end caps, etc., especially varnished wire, skeleton and magnets.


High temperature motorsfrom oyostepper.com are rated to operate in ambient temperatures between 50 degrees C and -20 degrees C. While this satisfies the majority of uses, there are certain applications that require the motor to operate at higher or lower temperature ranges than what standard motors allow for. Unfortunately, operating standard motors anywhere outside these temperature ranges will result in poor performance.

High Temperature Stepper Motor Frame size selection:

High Temperature Stepper Motors are typically made in groups or families, the families are identified by the outer diameter or size of the square, these references are called frame sizes. In the American system, a 23 frame is a nominal 2.3 inches in diameter. For High Temperature Stepper Motors less than one inch in diameter, the reference is typically known as a size. Herein is a list of the frame sizes offered by Empire Magnetics Inc. and some of the characteristics of the group that will allow you to select from them.


Magnet performance degrades at high temperatures unless a special alloy with high-temperature tolerance and high curie point is used—similar to what might be used in a space or vacuum motor depending on the application. For these applications, the wire has to have special insulation that can tolerate high heat as well. Upgraded insulation also helps to reduce stress fractures doe to heat-up and cool-down cycles. Type II motors require additional insulation material to prevent burnout.


Currently, the high temperature motors in our catalog are of class H, which allows a maximum temperature of 180 degrees Celsius and an allowable temperature rise of 125 degrees Celsius.

Of course, we can also customize stepper motor of other levels of high temperature motors, so you can contact our technical team.

How to Choose the Right Pancake Stepper Motors for Your Needs

A step motor is a type of electric motor that uses a series of electrical pulses to move the rotor. The rotating rotor causes a linear actuator, which produces motion in one direction. The pancake stepper motor is a type of step motor that has the capability to rotate continuously in both directions without any need for periodic rotary encoder. It is also known as the "pancake" stepper because it resembles a pancake, with its flat shape and circular cross-section. This article discusses how this type of step motors work and their applications in industrial machinery such as 3D printers, CNC machines, and robotics. What Makes the Pancake Stepping Motor Different From Others? The pancake stepping motor is a type of electric generator that uses an electromagnet to produce electricity. It is also known as the pancake motor because it looks like a pancake when it is folded in half. It has been around since the 1970s, but it saw a surge in popularity after the Fuk

What’s the difference between servo and closed loop stepper motors?

Servo and  closed loop stepper motor  have similar construction and share the same fundamental operating principle. Both motor types incorporate a rotor with permanent magnets and a stator with coiled windings … and both are operated by energizing or applying a dc voltage to the stator windings. That then causes the rotor to move. However, this is where the similarities between servo and stepper motors end. Drive methods for stepper motors Stepper motors have 50 to 100 poles and are two-phase devices. In contrast, servo motors have between four and 12 poles and are three-phase devices. What is more,  stepper motor driver  generate sine waves with a frequency that changes with speed … but with an amplitude that is constant. Servo drives, on the other hand, produce sine waves with variable frequency and amplitude — allowing them to control both speed and torque. Control methods for stepper motors Traditional stepper motors move when they receive a command to advance a cer

What drivers Can i use on NEMA 17 motor or NEMA 24?

Description Nema 17 motor  is not standard for electrical characteristics of the stepper motor. It is just faceplate and mounting holes standard to make it easier to interchange motors. Most likely you have to check from the specification that what is rated current for that motor and is it unipolar or bipolar one. Choose driver based on that. Note: Drive can always be more powerful than the motor, but you have to limit your current from the drive side. It’s also possible to use chopper drives with the less current rating, but then your motor runs underpowered. But one can definitely make assumptions on the motor size that NEMA 17 could use 1A – 2A current and  NEMA 23 motor  could use around 2A – 5A current. How to run a stepper motor without a microcontroller? It’s totally possible since the drive doesn’t care where it gets it’s stepping impulses. You only need some kind of source for pulses and direction. The simplest option would be to use a NE555 timer chip.
