Series Braking Unit User Guide.
6.4 Selection of Applicable Motor
The standard applicable motor is a four-pole squirrel-cage asynchronous induction
motor. For other types of motor, select a proper AC drive according to the rated motor
current.
The cooling fan and rotor shaft of non-variable-frequency motor are coaxial, which
results in reduced cooling e󶍽ect when the rotational speed declines. If variable speed
is required, add a more powerful fan or replace it with variable-frequency motor in
applications where the motor overheats easily.
The AC drive may alarm or even be damaged when short-circuit exists on cables or
inside the motor. Therefore, perform the insulation short-circuit test when the motor
and cables are newly installed or during routine maintenance. During the test, make
sure that the AC drive is disconnected from the tested parts.
For details about the recommended motor models, see
