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.
Typically the three phase AC induction motor
drive is used in the pump.
Matlab/Simulink model of AC induction motor
controlled by constant slip method with motor speed stabilization
Independent market research shows that ABB is the world's number one manufacturer of low voltage AC induction motors
When choosing an AC induction motor
, two factors come into play-efficiency rating and type of enclosure.
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.
The electric Tiago will be available with a three-phase AC induction motor
that will generate peak power of 30kw at 4500rpm.

slip." Electrical Construction and Maintenance (4), Penton, NY, NY.
Further, in many cases, the motor will be one full frame size smaller than the alternative AC induction motor
, reducing weight, cost, and possibly VFD size.
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 electric transaxle's ac induction motor
can supply a peak power output of 96 hp (67 kW) to the wheels.
