Servo motors are limited in horsepower compared with
AC induction motors, so the application of multiple servo motors may be needed for higher power requirements.
The market of the advanced water supply systems based on the pumps with the
AC induction motor drives controlled by the frequency converter increases rapidly nowadays.
Transients of
AC induction motor, speed (a), stator current (a) and rotor slip (b) at nominal load and 1200 rpm speed, motor is controlled by scalar method
VSDs also known as variable frequency drives, or VFDs) for
ac induction motors dominate the marketplace.
Independent market research shows that ABB is the world's number one manufacturer of low voltage
AC induction motors by revenues.
An
AC induction motor is one of the simplest and least expensive motor technologies and hence the most applied,' explains Tim Albers, director of marketing for the industrial motors division of Emerson Motor Company (888-637-7333, www.
MultiMix's motor is an electric three-phase
AC induction motor running from the variable frequency supplied by its inverter which is fed from a common household single-phase outlet.
These include an
AC induction motor, a brushless PM synchronous motor, a switched reluctance (SR) motor and a synchronous reluctance motor.
Curtis has introduced three
AC Induction Motor Controllers: Models 1230, 1236 and 1238, designed for 24-80V battery systems, with 60-800Arms 2 minute current ratings, and targeted for a wide range of battery powered vehicles.
NovaTorque is a producer of Electronically Commutated Permanent Magnet (ECPM) motors that deliver the superior energy efficiency of permanent magnet motors at price points more comparable to the common
AC induction motor.
The control unit on the drive provides three-phase (380V to 690V)
AC induction motor control with an easy-to-use IPS1 interface card and connecting cables.
The package consists of a brushless dc motor and speed control unit for 10, 25, 40, and 90 W output power, and the motor is less than half the size of an equivalent
ac induction motor, with lengths of 1.
