Temperature rise in a motor is the difference in temperature between the motor and its environment, caused by the heat generated during its operation. Generally, stepper motors are equipped with Class B insulation, which means the internal temperature should not exceed 130 degrees Celsius. In high-temperature environments, it's advisable to use high-temperature-resistant stepper motors, such as Class H.

Temperature rise in a motor is the difference in temperature between the motor and its environment, caused by the heat generated during its operation. Within the motor, there are components like the iron core and the skeleton.

How to Choose a Linear Stepper Motor?

In our product series, we also offer non-captive linear motors in addition to providing external nut linear motors.
The working principle of the non-captive linear motor is to integrate the nut with the motor rotor into one, and the screw shaft passes through the center of the motor rotor.

When in use, fix the screw and prevent it from rotating, when the motor is powered on and the rotor rotates, the motor will move in a straight line along the screw; Conversely, if the motor is fixed and the screw is prevented from rotating, the lead screw will move in a straight line.

Common problems and analysis in stepper motor applications: out of step. This means that the actual position of the motor is inconsistent with the command position during operation. This may be caused by excessive motor load, insufficient driver current, improper driver subdivision number setting, etc. The solution to this problem is to reduce the motor load, increase the driver current, adjust the driver subdivision number, etc.

Common problems and analysis in stepper motor applications: does not run after power on. This may be caused by improper driver parameter settings, poor connection between motor and driver, motor failure, etc. 1) Check whether the connection between the motor and driver is good and whether the start command is received correctly; 2) Check whether the control system has sent a pulse signal to the stepper motor driver and whether the driver parameter settings are correct; 3) Check the motor itself for failures: whether it is overloaded and blocked (the motor usually makes a whistling sound at this time); whether there is an abnormality (you can check whether it is stuck or jammed by rotating the motor shaft).

Rotor rotor is the rotating part of the motor. It rotates under the action of the magnetic field generated by the stator to realize the mechanical movement of the motor (each time an electrical pulse signal is input, the rotor will rotate at a fixed angle). The shaft, as the core component of the rotor, transmits the rotational motion to the external load. The rotor's design and material selection directly affect the motor's output torque and rotation accuracy.

Stator stator core is the motor's stationary part and provides the magnetic field's basic structure. The stator winding is tightly wound on the core, and when current passes through it, a magnetic field is generated. This magnetic field interacts with the magnetic field of the rotating part (rotor), thereby driving the rotation of the rotor. The design of the stator has an important impact on the performance and accuracy of the stepper motor.

The basic structure of a stepper motor is mainly composed of front and rear end covers, bearings, center shaft, rotor core, stator core, stator assembly, corrugated washers, screws, etc. As a motor that can rotate according to a specific number of steps, the components and functions of the stepper motor are crucial to realize its position control function.

In a sealed environment such as a control panel or near a heating element, the ambient temperature will rise. When installing the motor, be sure to set ventilation holes and pay attention to the increase in ambient temperature. Do not install it near a vibration source or in a place where vibration can easily affect the motor.
