The three-phase synchronous motors MKE037, -047, -098, -118 are used for operation with drive systems.
The motors feature pressurized encapsulation, are non-ventilated, servo-controlled
permanent magnet special motors for use in potentially explosive 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 motor speed is
varied by changing the frequency of the supplied power.
The drive frequency and the
voltage are changed by fast pulse width modulation of a bus voltage.
The current waveform used is sinusoidal.
The motors are brushless designs with a resolver or an optical encoder.
