Product description
The MKE037, -047, -098, -118 three-phase syn-
chronous motors are used for operation with
drive systems. The motors are flameproof, non-
ventilated, servo-controlled permanent magnet
special motors for use in hazardous areas with a
free internal volume of 300 cu. in. or less. The
motors are controlled by a pulse width modulated
(PWM) variable frequency drive. The speed of the
motor is varied by changing the frequency of the
power supplied. The drive frequency and voltage
are changed by fast pulse width modulation of a
bus voltage. The used current waveform is sinus-
oidal.
The motors are brushless designs with a resolver
or optical encoder.
