Bj42d15 26v10 Stepper Motor Datasheet Exclusive » ❲ORIGINAL❳

Here’s a standout feature you could highlight in a product description, blog post, or technical summary for the BJ42D15 26V10 Stepper Motor, based on common high-performance hybrid stepper motor specs (assuming this follows typical naming conventions for a NEMA 42 frame motor).

2. Identification & Naming Convention

To understand the motor's physical and electrical nature, one must decode the nomenclature:

  • BJ: Manufacturer or Series Code (often denoting a specific Asian OEM standard).
  • 42: Indicates the faceplate dimensions. "42" corresponds to 42mm x 42mm (NEMA 17 standard).
  • D: Body Length/Stack Type. In this classification, "D" typically represents a body length of approximately 34mm to 40mm (often referred to as a "short stack" or "D-length").
  • 15: Designates the step angle or construction type. In this context, it usually refers to the standardized hybrid construction, but in specific OEM charts, it can denote the motor length code.
  • 26V10: The critical electrical specification.
    • 26V: Often refers to the recommended voltage range or a test voltage parameter (typically rated for 24V-36V systems).
    • 10: Denotes the current rating per phase, typically 1.0A to 1.2A (or 10mA in rare low-power variants, though 1.0A is standard for this frame).

General Specifications

| Parameter | Value | Unit | | :--- | :--- | :--- | | Frame Size | NEMA 17 (42mm) | mm | | Step Angle | 1.8° (200 steps/rev) | Degrees | | Motor Type | Hybrid Stepper | - | | Number of Phases | 2 | - | | Rotor Inertia | ~54 to 68 | g-cm² | | Weight | Approx. 0.28 – 0.35 | kg |

Why this matters for your application:

  • CNC routers, laser cutters, or industrial pick-and-place machines get faster settling times and less audible noise.
  • Works perfectly with 26V stepper drivers (e.g., Leadshine DM860 on reduced voltage) for cost-effective high-torque solutions.

If you need the full datasheet (step angle, inductance, detent torque, wiring diagram, etc.), I can help format it into a clean spec sheet. Just let me know.

Stepper Motors in 3D Printing: Characteristics & Practical Guidelines

BJ42D15-26V10 is a NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd. and is most commonly found as original equipment in Creality 3D printers

(e.g., Ender 3, CR-10 series). Despite its ubiquity, official manufacturer datasheets are often restricted to OEM partners, making technical specifications difficult to source for end-users. Technical Specifications

Based on technical data for the BJ42D15 series used in similar 3D printing applications:

BJ42D15-26V10 is a specialized NEMA 17 hybrid stepper motor manufactured by Hunan Keli Motor Co., Ltd.

. It is widely recognized as a stock component for the X, Y, or Z axes in Creality 3D printers , such as the Ender 3 series. Technical Specifications Here’s a standout feature you could highlight in

Based on manufacturer data and verified community testing, the BJ42D15-26V10 typically adheres to the following parameters: Motor Type : 2-Phase Hybrid Stepper Motor. Step Angle : 1.8° (200 steps per revolution). Rated Current : 0.84A per phase.

: While some generic 42-34 motors are rated at 1.5A, the BJ42D15 series used by Creality is specifically tuned for lower current (~0.84A) to maintain thermal stability. Holding Torque : Approximately 2.86 kg·cm (0.28 N·m). Dimensions : 42 x 42 x 34 mm (Standard NEMA 17 "42-34" frame). Shaft Diameter Input Voltage : Maximum 24V DC. Operational Features Stepper Motor Basics

BJ42D15-26V10 is a high-precision NEMA 17 stepper motor frequently utilized in 3D printers, specifically as a replacement part for Creality machines like the Ender-3 S1, Ender-5 S1, and V3 series. Technical Specifications

Based on manufacturer data and community testing, the core specifications for the BJ42D15-26V10

(often referenced interchangeably with similar "42-26" models) include: Step Angle: 1.8 raised to the composed with power (standard 200 steps per full rotation). Rated Current: 0.84 Amps per phase. Motor Frame Size: NEMA 17 (approximately 42mm x 42mm). Body Length: 26mm (indicated by the "-26" in the part numbering). Phase Count: 2-Phase bipolar. Key Performance Insights Current Limit Warning:

While some online communities erroneously assume these motors can handle 1.5 Amps, official specifications for the BJ42 series indicate a much lower rated current of BJ: Manufacturer or Series Code (often denoting a

. Operating above this threshold significantly increases heat and risk of motor failure. Voltage Calibration (Vref):

To ensure optimal performance without overheating, users often adjust the stepper driver voltage (Vref). For a 0.84A rated motor on common Creality boards

, this usually translates to a specific Vref setting based on the driver type used (e.g., TMC2208 or A4988). Compatibility: This motor is standard for X, Y, and Z axes on several Ender and CR series printers due to its balance of torque and compact size. Identification and Variants The BJ42 series follows a specific naming convention: Refers to the internal coil and winding configuration.

Refers to the physical length of the motor body in millimeters.
