Stator
Stator in TMRW/TM-2/IM-2 series does contain water cooling channel. The outer casing is made of
aluminum alloy or steel, and the inner part is composed of iron core, coils, covered with epoxy. There
are two cable outlets on one side, motor power cable and temperature sensor cable. Stator should
be installed on the fixed part of customer's machine.

Rotor
The main structure is a steel ring with evenly attached magnets. Rotor should be installed on the
rotating part of customer's machine. Due to its strong magnetic suction, well protection is needed
during assembly and handling. To avoid danger, keep it away from magnetic conductors (e.g. iron
objects).
