1 Introduction to the Product
The IndraDyn A series consists of housed, asynchronous motors from
Bosch Rexroth. The two versions of IndraDyn A differ by their method of
cooling.
•
The
MAD version
is air-cooled by a firmly-attached fan unit, which
forces the ambient air across the surface of the motor.

•
The
MAF version
is internally cooled by liquid.

IndraDyn A motors can be used either as main-spindle motors or as servo
motors for all rotary drive applications.
The optimized design has international protection class IP65 for both
motor and fan which allows for operation in adverse conditions. The easy-
to-service construction reduces maintenance frequency and even allows
maintenance during operation.
Combined with digital control devices from the IndraDrive series, this
results in intelligent drive solutions with a high power density and open
functions.
