    for commutation; instead, they are electronically commutated. BLDC motors have many advantages over brushed DC motors and induction motors. In addition, the ratio of torque delivered to the size of the motor is higher, making it useful in applications where space and weight are critical factors
  • Replacing Your DC Motors? Think AC
    . Modern AC motors and drives provide a number of additional operating benefits that rival those traditionally available only from DC drives. For example, today's drives can now produce full torque at start-up, something that once was impossible. They also are capable of speed ranges of 1,000:1 vs
