What are the key characteristics of the stepper motors?

They are known for high torque output, low noise, and robust construction. They typically have a step angle of 1.8 degrees and offer precise positioning control, making them ideal for applications requiring accuracy and strength.

Does it require a specific power supply?

Yes. For optimal performance, we recommend a 12-24V DC power supply. Lower voltages will result in reduced torque. Additionally, while higher current settings increase torque, they also result in more significant motor heating.

What is the recommended operating speed range for YEJMKJ stepper motors?

The higher the speed, the lower the torque. Recommended speed range: 0-600 rpm for open-loop motors.

What applications is this stepper motor compatible with?

The motor delivers high torque, making it ideal for projects that require accurate positioning. The stepper motors find widespread use in applications such as CNC routers, engraving machines, DIY robot, and industrial automation systems.

What are the environmental operating conditions for this stepper motor?

YEJMKJ stepper motors are built to perform in a wide range of environments, with an operating humidity range of 15% to 95% RH and a temperature range of -20°C to +50°C (-4°F to 122°F).
