NEMA34 1.2° / 1.8° HYBRID STEPPER MOTOR

What is the difference between the 1.2 degree and 1.8 degree variants in this motor family?

The 1.2 degree model 86HC97-5806A14-B35 is a 3-Phase motor with rated voltage 5.22VDC and holding torque 4.5 N.m. The 1.8 degree variants are 2-Phase motors with different voltages and torques, for example 86HS78-4004A14-B35-04 is 1.52VDC with 3.5 N.m, 86HS100-5004A14-B35 is 2.5VDC with 6.5 N.m, and 86HS156-5504A14-B35 is 3.85VDC with 12 N.m.

What are the electrical specifications for these variants?

Specifications vary by model. The 1.2 degree 3-Phase unit uses 5.22VDC and 5.8A, while the 1.8 degree 2-Phase units range from 1.52VDC at 4.0A to 3.85VDC at 5.5A depending on the variant such as 86HS78-4004A14-B35-04, 86HS100-5004A14-B35, and 86HS156-5504A14-B35.

What are the shaft and length specifications?

The shaft is round with a 14 mm diameter and a 5 mm square cut section, 35 mm long. Motor lengths vary by model, with 97 mm for the 1.2 degree unit, 78 mm for the 1.8 degree units, and 156 mm for the high torque variant.

What torque values are available across the models?

Holding torques range from 3.5 N.m to 12 N.m. The 1.2 degree model provides 4.5 N.m, while the 1.8 degree variants offer 3.5 N.m, 6.5 N.m, or 12 N.m depending on the specific model.

What insulation and safety features are included in these motors?

Dielectric strength is 500 VAC for 1 min at 5 mA, insulation resistance is at least 100 MOhm at 500 VDC, insulation class is B, and wires are AWG26 UL1007. The surface is black electrophoresis.
