High Temperature Stepper Motor
Generally speaking, high temperature resistant motors are defined by their insulation class. The field of stepper motors usually involves six insulation classes.
|Temperature class of insulation||A||E||B||F||H||C|
|Maximum allowable temperature (℃)||105||120||130||155||180||220|
|Winding temperature rise limit (K)||60||75||80||100||125||150|
High temperature resistant 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.
Varnished wire is a very critical component in high-temperature environments, because ordinary grade enameled wire will soften or even melt under high-temperature conditions, and once that happens, the direct result is the destruction of the motor. For the high temperature situation, we choose the insulation class H level varnished wire, which can withstand a temperature of 180 degrees Celsius (356 degrees Fahrenheit), which can ensure that the motor does not have any softening or melting in the case of 180 degrees Celsius.
Magnets are another important component, because the magnets inside the stepper motor are a material that is easily affected by temperature. The magnets are susceptible to demagnetization at high temperatures, which can lead to a sharp decline in torque. By choosing high temperature resistant magnets, demagnetization can be avoided, thus ensuring that the motor can provide a stable torque.
The main purpose of the skeleton is to support the motor stator coil windings, and its main material is plastic. Therefore, it is necessary to use high temperature resistant material to ensure that the skeleton will not be deformed.
