A stepper motor is an electric motor whose main feature is that its shaft rotates by performing steps, that is, by moving by a fixed amount of degrees. This feature is obtained thanks to the internal structure of the motor, and allows to know the exact angular position of the shaft by simply counting how may steps have been performed, with no need for a sensor.

This motor is desighed for high temperature application. We have customed motors winding, bearing, magnetic steel and also the plastic skeleton to achivel insulation class of H, the teprature reach up to 180C degree. This motor is widely used in 3D Printer.

Nema 11 Frame Size: Nominal outer dimension of 1.1 inches, these motors are very low power, suitable primarily for instrumentation applications. Torque range of .5 to 2.5 oz-in. Cylindrical shaped motor with square front flange.

Nema Frame Size 17: Nominal outer dimension of 1.7 inches, these motors are relatively low power useful for a wide range of industrial applications. Torque range of 13 to 26 oz-in. Cylindrical shaped motor laminations, with square end flanges front and rear. Since this High Temperature Stepper Motors does not have a housing, it is not available in all environments.

NEMA 23 Stepper Motor: Nominal outer dimension of 2.3 inches. Extremely popular size useful for a wide range of industrial applications. Torque range of 60 to 150 oz-in. 

Nema 34 Stepper Motor: Nominal outer dimension of 3.4 inches. Power range of 80- 240 watts, useful for a wide range of applications. Torque range of 150 to 450 oz-in. 

Nema Frame size 42: Nominal outer dimension of 4.2 inches. Power range of 240-700 watts, relatively high power in the High Temperature Stepper Motors range. Torque range of 400 to 1600 oz-in. 

 NEMA 17 stepper motor with 0.9 degree step with a torque holding 0,6Nm. It is also ideal for 3D printers, CNC machines and other DIY projects. This stepper motor from LDO Motors can tolerate up to 180 celcius winding temperature.

Through the use of higher grade, specially formulated materials, motors can be designed for extreme temperatures well beyond what a standard motor can withstand. Other factors that can affect motor use in extreme temperature situations includes how often the load is applied. Most standard motor ratings are for continuous duty operation, but if your load cycling specifications are anything less than continuous, it will affect your motor selection process.
