Information 2-1

MN718

Overview

The Baldor Series 18H PWM control uses flux vector technology

. Flux vector technology

(sometimes referred to as Field Oriented Control) is a closed loop control scheme using

an algorithm to adjust the frequency and phase of voltage and current applied to a three

phase induction motor

. The vector control separates the motor current into it’

s flux and

torque producing components. These components are independently adjusted and

vectorially added to maintain a 90 degree relationship between them. This produces

maximum torque from base speed down to and including zero speed. Above base

speed, the flux component is reduced for constant horsepower operation. In addition to

the current, the electrical frequency must also be controlled. The frequency of the

voltage applied to the motor is calculated from the slip frequency and the mechanical

speed of the rotor

. This provides instantaneous adjustment of the voltage and current

phasing in response to speed and position feedback from an encoder mounted to the

motors’ shaft.

The control’s rated horsepower is based on the use of a NEMA design B four pole motor

and 60Hz operation at nominal rated input voltage. If any other type of motor is used, the

control should be sized to the motor using the rated current stated on the motor

nameplate.

The Baldor Series 18H control may be used in many dif

ferent applications. It may be

programmed by the user to operate in four dif

ferent operating zones; standard or quiet

constant torque or variable torque. It can also be configured to operate in a number of

modes depending upon the application requirements and user preference.

It is the responsibility of the user to determine the optimum operating zone and mode to

interface the control to the application. These choices are made with the keypad as

explained in Section 4 of this manual.
