WHEELTEC BM50 Integrated Driver Brushless Motor

The WHEELTEC BM50 is an integrated driver brushless motor designed for robotics developers, educators, and makers. Combining a high-speed brushless motor with built-in drive and control circuitry, it offers a compact, low-noise solution for advanced motion control. This versatile motor is ideal for precision robotics projects requiring reliable speed and torque feedback.

Integrated drive and control

The BM50 features integrated drive and control circuitry alongside AB-phase encoder output, delivering a highly compact and quiet high-speed motor solution. This patented design, with utility patent number 202422729396.5, simplifies wiring and saves valuable space inside your robotic chassis.

Robust electrical performance

Operating on a rated voltage of 12V with an input range of 8-15V, this motor delivers a rated power of 28W and a peak power of 57.6W. It features 12 stator slots, a Y-type winding, and 5 pole pairs, ensuring efficient power delivery with a maximum no-load current of 0.65A.

Planetary gearbox option

Choose between the standard BM50 and the geared version, which features a 42-series planetary gearbox with a 1:19 reduction ratio. The geared version increases rated torque from 60 mN.m to 1.14 N.m, while peak torque rises from 423 mN.m to 8 N.m for heavy-duty applications.

Precise feedback and encoder resolution

The integrated encoder provides 20 state transitions per revolution on the standard model, which increases to 380 transitions per revolution on the geared version. This high-resolution feedback allows for precise closed-loop speed and position control in demanding robotics projects.

Compact mechanical dimensions

With an outer diameter of 48mm, the standard motor is just 28mm long and weighs 174g, or 191g with the extended metal bracket. The geared version has a length of 72mm, a weight of 510g, and features a robust 10mm diameter output shaft compared to the standard 6mm shaft.
