Brushless DC Motor

KNF’s BL30 DC motor for liquid and gas OEM diaphragm pumps offer high torque in a smaller size.

September 19, 2012   by Design Engineering Staff

KNF introduced a small brushless DC motor (Type BL30) as standard and readily available for integration into a wide range of liquid and gas diaphragm pumps for OEM applications. The motor (with outside diameter of 32mm) is designed to fit within standard compressor housings. The BL30 motor can be supplied in 12V or 24V versions configured either as 2-wire (for power input) or 4-wire solutions (for power input, tachometer output, and speed control signal input). All provide protection against reverse polarity, over-voltage, and over-temperature, and motors additionally are IP54 rated.
