The integral control option for the 2.25” has a standard input voltage range of 12-48 VDC. If an external controller is used, customer’s controller will determine the voltage range of the motor. However, BLDC motors do not accommodate high voltage inputs (<48VDC) due to IEC creepage and clearance requirements.
 

Yes, with the elimination of brushes, BLDC motors can be regulated to slower operating speeds without sacrificing torque. Brushless motors can also utilize skewed magnets to reduce the effect of cogging.
