Rexroth IndraDyn T Application Notes 9-3
DOK-MOTOR*-MBT********-PR03-EN-P
9.3 International Protection Class
The degree of protection is defined by the abbreviation IP (International
Protection) and two reference numbers specifying the degree of
protection. The first reference number describes the degree of protection
against contact and penetration of foreign bodies; the second reference
number describes the degree of protection against water.
Protection class IP00 according to IEC 60529:1989 + A1: 2000 applies for
the stator and rotor of the IndraDyn T series. The applicability for certain
conditions of the IndraDyn T motors must be checked carefully.
Heed the following list (without any guarantee for completeness).
• Use of the motor in a damp environment or a high-humidity
atmosphere.
• Use of cooling lubricants, aggressive materials or other liquids.
• Cleaning procedures with high pressures, steam or jets of water.
• Chemical or electro-chemical interaction with subsequent corrosion or
decomposition of motor parts.
• Damage of the winding insulation and irreparable damage of the
motor.
• Plan suitable covers or seals to protect the motor.
• Use only cooling lubricants and other materials that have no
aggressive or decomposing effect on the motor parts.
• Do not clean with high pressures, steam or jets of water.
The machine manufacturer is responsible for the testing and
execution of suitable measures.
9.4 Compatibility
All Bosch Rexroth control and drive devices are developed and tested
according to the state of the art.
However, since it is impossible to follow the continuing further
development of every material with which our controls and drives could
come into contact (e.g. lubricants on tool machines), reactions with the
materials that we use cannot be ruled out in every case.
For this reason, you will have to carry out a test for compatibility among
new lubricants, detergents, etc. and our housing and device materials.
9.5 Motor Cooling System
The heat of the transformed motor power loss P
V
is dissipated using the
cooling system. IndraDyn T motors may be operated only if the supply of
coolant is ensured. The cooling system must be rated by the machine
manufacturer in such a way that all requirements regarding flow,
pressure, purity, temperature gradient etc. are maintained in every
operating state.
