Frequently Asked Questions

What is a hybrid stepper motor?

A hybrid stepper motor combines the principles of variable reluctance and permanent magnet motors. It offers high torque, precise control, and smooth operation, making it ideal for CNC, robotics, and automation.

How does a 48V brushless DC motor work?

A 48V brushless DC motor uses electronic commutation instead of brushes. External driver circuits control the current flow through the windings, enabling high efficiency, low maintenance, and long life.

Why is my hybrid servo stepper motor hot?

It's normal for stepper motors to get warm during operation. Hybrid servo motors can reach 70-80°C under load. As long as there's no burning smell or smoke, this is within safe operating limits.

Do you offer custom motor solutions?

Yes, Dewo provides OEM and ODM services. We can customize voltage, shaft, encoder, gear ratio, and other parameters based on your application needs.

What is the delivery time for bulk orders?

Standard products ship within 7-15 days. Custom orders may take 20-30 days depending on complexity. We provide tracking and logistics support.
