MOTOR DRYOUT SYSTEM

Automated Motor Winding Dryout System

The conventional process of drying out motor windings involves the tedious task of
circulating current with welding machines. This could be a very
labor-intensive process andcan cause winding and insulationdamage in the motor as well as damage to the welding power supply.

Proven Field and Shop Uses

Efficient Drying of Motor/Generator Windings up to Several Thousand Horsepower
Expedited Endturn Re-Treatment Resin Cure on Motors/Generators
Curing of B-Stage insulation and Hydro-Electric Generator Pole Pieces.
Even Heating of Windings to Perform Quality Checks by Winding Connections via Thermography.
Programmable DC Current Source, 0-1200A.

Controlled Monitoring and Data Recording

The ADM process is continually monitored on a Time/Temperature trend chart that is
always displayed on the screen. Pertinent data is logged to a disk for future analysis.

The 1200 ADM incorporates a touch screen Pentium
computer in the operator's console that provides the Man/Machine interface, allowing an operator to change
modes of operation or significant parameters in a given
mode.

System Safety Features

Internal Breaker Protection.
Automatic Shutdown on Loss of Temperature Signal.
T/C-RTD Scanner Selects Hottest of 3 Connected Sensors to Control Process.
Rotating Strobe Light Indicates Mains Power Applied to Primary Power
Transformer. The Computer Screen will flash a warning and Strobe Extinguishes
in Event of Anomaly.
External Panel Electrical Interlock System Prevents Application of Power when
Panels are not in place.
Positive Mechanical Breaker Selection Feature Permits Operation of System from
either 60amp or 200A Connected Service.
Software Password Protection Prevents Unauthorized System Parameter
Changes.
Connected Windings Grounded between Switching to Eliminate Residual Current/Voltage.
Switching Delay Feature Prevents Operation of Contactors When Powered.

Cost Efficient Solution

The Series 1200ADM from Mannings USA addresses all aspects of this problem.
The Automated Motor Winding Drying Machine (ADM) provides for fully automatic
temperature control in the motor windings. Its capabilities include: operator
adjustable current limiting, temperature rate-of-change and duration to be held
at the dryout temperature. It also provides for fully automatic switching of current
through the windings assuring uniform heating of all windings.
