Product Description:
The 5210 is a two-phase stepper motor built by Pacific Scientific and supplied as part of the 5000 Stepper Motors series. Designed for incremental positioning tasks, the unit translates pulse-train commands from a motion controller into precise shaft rotation that can be directly coupled to lead screws, belt drives, or indexing tables on assembly lines and test equipment. Its electrical interface and environmental limits are matched to low-to-mid-power automation where compact dimensions and simple open-loop control are preferred.
The motor windings are energized from a bus that may be as high as 40 VDC or as low as 12 VDC, giving designers a wide supply range for portable or cabinet installations. Command logic arrives as step and direction pulses; the device can count up to 20,000 pulses/s and still accept individual commands that are only 500 ns long, allowing tight micro-stepping resolution. Each phase can draw up to 2.5 A while the MOSFET bridges present a maximum on-state resistance of 0.45 Ω, limiting conduction loss. A saturation voltage of 1.35 V at 3 A and a diode clamp drop of 1 V further describe the voltage overhead reserved for protection and current regulation.
Current regulation is achieved with pulse-width modulation that switches at 17 kHz, keeping audible noise low while maintaining torque linearity. Control electronics operate from a dedicated 5 VDC logic rail that is isolated from the power bus to protect PLC outputs. The motor can run in ambient temperatures up to 50 °C and tolerate relative humidity levels of 90% without condensation. For seasonal storage it remains functional between -40 and 85 °C, with the lower extreme of -40 °C safeguarding magnets and insulation; pulse inputs must respect the minimum 0.5 µs step clock width for reliable wake-up.
