Expert FAQ: Precision Stepper Motors

Common technical and customization questions answered by the Zentec engineering team.

❓ What are the primary differences between hybrid and permanent magnet (PM) stepper motors?
PM stepper motors use permanent magnets in the rotor structure, providing a cost-effective solution with step angles between 7.5° and 18°. Hybrid stepper motors combine features of PM and variable reluctance motors, allowing smaller step angles (0.9° to 1.8°) and higher holding torque.
❓ How does a planetary gearbox improve micro stepper motor performance?
A planetary gear reducer lowers output speed while scaling up torque proportional to the reduction ratio. Additionally, inline planetary gearheads minimize angular play, which improves positional accuracy in automated actuators and analyzers.
❓ Can Zentec customize shaft diameters, lead wires, and connectors?
Yes. As an OEM/ODM manufacturer, we customize shaft profiles (D-cuts, slots, threads), winding resistances, lead wire lengths, and electrical connectors to match your product's design requirements.
❓ What testing procedures do you use to verify product lifespan?
We perform automated lifecycle tests under simulated mechanical loads, alongside temperature-humidity cycling, salt spray exposure, and vibration profiling. This helps ensure reliability across all manufacturing runs.
