Brushless Motor/Three-phase/28BYA Series

Product catalog summary
General Specifications:
The 28BYA Series of Brushless DC Motors features a YWE winding type and a Hall effect angle of 120 degrees electrical angle. The radial play is 0.02mm with a 450g force, and the end play is 0.08mm with the same force. The maximum radial force is 15N at 10mm from the flange, and the maximum axial force is 10N. The insulation class is B, with a dielectric strength of 500VDC for one minute and an insulation resistance of at least 100MΩ at 500VDC.
Model Specifications:
The series includes three models: 28BYA026A080X-01, 28BYA038B031X-01, and 28BYA077B031X-01. All models have 4 poles and 3 phases. The rated voltage is 15VDC for the first model and 24VDC for the other two. Rated speeds are 8000 RPM for the first model and 3100 RPM for the others. Continuous stall torque ranges from 8.4 mN.m to 60.00 mN.m, while rated torque ranges from 7 mN.m to 50.00 mN.m. Rated power varies from 5.2W to 16W. Peak torque and current are also specified, with peak torque ranging from 21 mN.m to 150.00 mN.m and peak current from 0.87A to 2.66A. The torque constant and back EMF are provided for each model, along with rotor inertia and body length.
Performance Data:
The voltage range for these motors is 12 to 36 VDC, and the speed range is 3000 to 8000 RPM. The weight of the motors varies from 0.06 Kg to 0.280 Kg.
