Electromagnetic Compatibility (EMC)
6.3.3
While the ultimate responsibility for a system’s EMC compliance lies with the system builder, the LinX motor’s
design provides good EMC performance as a system component. The aluminum forcer housing that contains the
motor windings effectively limits both radiated noise emission from the motor during operation and external
sources of noise from impacting connected electronics.
The following are general recommendations when using the LinX motor to minimize Electromagnetic Interference
(EMI) in the system.
Keep all cable routing as short and direct as possible.
Separate low voltage signal cables from power cables and noisy components.
Ensure cable shielding is terminated correctly.
Other sources of EMI in the system, such as servo drives, must also be considered for EMC, refer to component
documentation for further information.
Servo Drive Configuration
6.4
In general, servo drives will need the following configuration to control the LinX motor. Servo drives that do not
specifically support linear motors can be configured as a two pole rotary motor. Configuration requirements will
depend on the specific servo drive and linear encoder used; refer to product documentation for specific
information.
