Shipping of online order is unaffected. Delivery may be delayed due to carrier backlog. Sorry for the inconvenience.

This is a 5v 28YBJ-48 Stepper Motor with Gear Reduction, so it has good torque for its size, but relatively slow motion. These motors/drivers are made by the millions for A/C units, fans, duct controls etc. which is why they are so inexpensive.

Specifications

  • 4 Phase 5 Wire Connection
  • Phase: 4
  • Current: 160 mA per winding (320 mA in 4-step mode) Measured: 250mA stopped, 200 mA running fast
  • Resistance: 31 Ω per coil winding (from Red wire to any coil) (Some 24-28 ohms)
  • Voltage: 5V DC
  • Step Angle (8-Step sequence: Internal Motor alone): 5.625° (64 steps per revolution)
  • Step Angle (4-Step sequence: Internal Motor alone): 11.25° (32 steps per revolution)
  • Gear Reduction ratio: 1 / 64 (Not really exact: probably 63.68395.:1 )
  • SO: it takes (64*64 = 4096 steps per output shaft revolution.. In 8-step sequence
  • SO: it takes (32*64 = 2048 steps per output shaft revolution.. In 4-step sequence
  • No-Load Pull-Out Frequency : 800pps
  • No-Load Pull-In Frequency : 500pps
  • Pull-In Torque : ≥ 78.4mN.m
  • Wiring Instruction : A (Blue), B (Pink), C (Yellow), D (Orange), E (Red, Mid-Point)
  • Weight : 30g

NOTE: Arduino "Stepper Library" runs in 4-step mode
