ACCESSORIES (continued)

Variable Speed Electric Motor

Reactors are normally equipped with a DC

variable speed motor supplied and controlled
through the Parr controller. Instructions for
connecting and operating these motors are
included in the controller instructions (e.g. No.
548M). This motor is usually installed in a drive
system designed to produce stirring speeds from
0 to 600 rpm. Higher speeds up to 1700 rpm
can be obtained by substituting larger diameter
motor drive pulleys.
