Brushless Motor/Three-phase/57BSB Series

Product catalog summary

General Specification:
The 57BSB Series Brushless DC Motors are designed with a winding type of YWE and a Hall effect angle of 120 degrees electrical angle. The motors have a radial play of 0.025mm at 460g and an end play of 0.025mm at 400g. They can withstand a maximum radial force of 75N at 20mm from the flange and a maximum axial force of 15N. The insulation class is B, with a dielectric strength of 500VDC for one minute and an insulation resistance of at least 100MΩ at 500VDC.

Performance Data:
The motors in this series have 8 poles and 3 phases, with a rated voltage of 24 VDC. They are available in different models with varying specifications:

57BSB076: Rated speed options of 1000 RPM and 3000 RPM, continuous stall torque of 0.36 N.m, rated torque of 0.3 N.m, and rated power of 31.5 W and 94.5 W respectively.
57BSB096: Rated speed options of 1000 RPM and 3000 RPM, continuous stall torque of 0.54 N.m, rated torque of 0.45 N.m, and rated power of 47 W and 141 W respectively.
57BSB116: Rated speed options of 1000 RPM and 3000 RPM, continuous stall torque of 0.72 N.m, rated torque of 0.6 N.m, and rated power of 63 W and 188 W respectively.

All models have a peak torque of 0.9 N.m, 1.35 N.m, and 1.8 N.m respectively, with corresponding peak currents of 5.6 A, 8.4 A, and 11.25 A at 1000 RPM, and 16.8 A, 25.2 A, and 33.5 A at 3000 RPM. The torque constant is 0.16 Nm/A at 1000 RPM and 0.053 Nm/A at 3000 RPM. The back EMF is 13 V/KRPM at 1000 RPM and 6 V/KRPM at 3000 RPM. Rotor inertia varies from 100 g.cm² to 200 g.cm², and body lengths range from 76 mm to 116 mm. The motors operate within a voltage range of 12 to 80 VDC and a speed range of 1000 to 3000 RPM. Weights range from 0.65 kg to 1.25 kg.
