Product Details
Please note kindly ask the price, because we cant disclose the price of any platform NEMA 17 STEPPER MOTOR JK42HS40-1704-13A: --- What it is It is a hybrid stepper motor, likely a NEMA 17 size (i.e. 42 × 42 mm flange) with a 40 mm body length. It has a 2-phase, 4-wire configuration. The step angle is 1.8 per step. --- Electrical / mechanical specs (approximate / published datasheet values) From datasheet / listings: Rated current: ~ 1.7 A per phase Resistance per phase: ~ 1.5 Ω (some listings) Holding torque: ~ 0.42 N·m (≈ 4.2 kg·cm) Dimensions: 42 × 42 × 40 mm (flange × body) Shaft diameter: ~ 5 mm (with flat) Key Spec: Holding Torque The holding torque is specified as 0.42 N·m (≈ 4.2 kg·cm) in its datasheet. Some listings also say "4.0 kg·cm" (≈ 0.40 N·m) as the holding torque. Another spec sheet shows 4.2 kg·cm (≈ 0.42 N·m) for this motor. So the motor can hold up to about 0.42 N·m of torque when stationary (i.e. resisting motion), under ideal conditions. --- What that means in practice Rotational load: If you convert that torque to a force at a lever arm, e.g. if you had a lever arm of 10 cm (0.1 m) from the shaft axis, then the motor could theoretically hold up a load of: F = \frac{\tau}{r} = \frac{0.42 \text{ N·m}}{0.10 \text{ m}} = 4.2 \text{ N} \approx 0.43 \text{ kg} (i.e. about 430 grams) in that configuration, neglecting losses (friction, gearing, dynamic loads, etc.) Dynamic conditions: Under motion (especially at higher speeds), the effective torque drops. So you cannot use full holding torque continuously under load at speed. Safety margin: It's wise to design for a lower torque margin, e.g. using only 30-70 % of the holding torque for reliable operation, to avoid skipping steps or overheating. Load type matters: If your load has inertia (i.e. heavy rotating elements), the motor might struggle to accelerate it even if holding torque is sufficient. --- If you tell me your mechanism (lever arm length, gear reduction, speed, orientation, etc.), I can estimate how much actual load weight this motor can realistically drive in your setup. Do you want me to compute that for your usecase?
