The 38BLF07 motor, measuring just 14mm long, provides a rated torque of 0.1Nm at 8000 rpm and a peak torque of 0.3Nm. Weighing only 57g, this motor is designed for dynamic movements with high acceleration and deceleration thanks to its low inertia.

Delta Line’s 38BLF07, a small yet powerful motor, aligns with its commitment to innovation and addressing customer needs. The company claims that the motors cater to the demands of handheld power tools, precision medical devices, and robotics where space is limited and high torque, efficiency, and size matter. Its frameless design allows seamless integration into devices or machines, enhancing overall efficiency and minimizing space.

Brushless DC motors present a range of benefits compared to their brushed counterparts. They provide a high torque to weight ratio, ensuring more power with less bulk. Efficiency is significantly increased as they offer more torque per watt. Their reliability is enhanced due to the absence of brushes and commutators, leading to reduced noise and a longer operational lifetime. Additionally, these motors eliminate ionizing sparks that typically come from the commutator in brushed motors, and they substantially reduce electromagnetic interference (EMI), making them a more stable and sustainable choice for various applications.
