A micro stepper motor with a lead screw is often used to create a linear actuator. It provides precise and controlled linear motion by converting the rotary motion of the stepper motor into linear motion through the lead screw mechanism.

1.Load Capacity: The 0.5kg load capacity refers to the maximum weight that the linear actuator can effectively move or hold. It indicates the maximum force the actuator can exert without compromising its performance. Make sure to consider the load requirements of your specific application to ensure the actuator can handle it.

2.Speed (600pps): The speed of 600pps indicates the maximum pulse rate at which the stepper motor can rotate. Each pulse corresponds to a step, and the speed is measured in steps per second. The actual linear speed of the actuator will depend on the lead screw pitch and the specific configuration of the system.

3.NEMA 8 Stepper Motor: NEMA (National Electrical Manufacturers Association) is a standard that defines the physical dimensions and mounting requirements for stepper motors. The NEMA 8 designation specifies the size and mounting dimensions of the motor. NEMA 8 motors are compact and typically have a smaller frame size and lower torque compared to larger NEMA sizes.
