Two-phase hybrid stepper motor series

CATALOGUE OVERVIEW

About this motor series

SYNTRON offers two-phase hybrid stepper motors for incremental positioning. The catalogue includes 28, 35, 39, 42, 56, 86 and 110 frame families with model-specific current, resistance and holding-torque tables. The listed step angle is 1.8 degrees.

As a selection example, the 42BYG250BK-0151 is listed at 1.5 A and 0.43 N·m holding torque. Holding torque describes the energized stationary condition, not available torque at running speed. Select the driver supply, acceleration and load from the torque-speed curve for the exact winding.

Selection priorities for Stepper motors

Holding torque is measured at standstill. Request a torque-speed curve at the actual supply voltage before choosing a motor for moving loads.

• Holding torque and step angle
• Operating speed and load inertia
• Phase current and winding
• Driver and supply voltage
• Open-loop or closed-loop feedback

Use the Two-phase hybrid reference when requesting a datasheet from SYN-TRON. Confirm these requirements against the exact offered model before comparing quotations.
