Exclusive Datasheet Breakdown

Because manufacturers often revise these models, exact figures can vary slightly. However, based on cross-referencing industrial parts catalogs, here is the definitive specification sheet for the BJ42D15-26V10.

Torque-Speed Curve Analysis

The BJ42D15-26V10 is characterized by a flat torque curve at lower speeds, making it ideal for high-precision positioning.

  • Pull-out Torque: At 1.0A, the motor generates approximately 0.32 N·m of holding torque. As the pulse frequency increases (RPM), the torque drops linearly.
  • Optimal Speed Range: 0 to 800 RPM. Beyond 1000 RPM, the torque drops significantly due to inductance, requiring higher drive voltages (48V+) to maintain performance.
