57 mm BLDC motor family for compact drive applications requiring stable continuous operation and speed feedback. These 24 V motors use star winding, 5 pole pairs, and Hall sensors as standard, with optional incremental encoder. Range covers 37.4 to 103.7 W nominal power and up to 0.33 Nm rated torque.
