5.1.4
The EPOS2 Module 36/2 features a built-in choke of 10 μH per phase. For most motors and applications
this will be sufficient. In case of high power supply voltage and for motors with very low inductance, the
current ripple will become too high thus, requiring additional chokes on the motherboard.
The minimum inductance of each choke can be calculated as to below formula.

Motor Phase

• If the result is negative, no additional chokes will be needed.
• If the result is positive, additional chokes will be required.
The chokes must have an electromagnetic shield, high saturation current, low losses and a
rated current higher than the continuous motor current. For recommended types "Supplier
Reference" on page 5-39.
