Figure 8.2: Maximum Supply Voltage regarding Motor Current and Inductivity 

 
Any combination of motor coil current and inductivity witch is above the curve for maximum supply voltage 
(V

S

) is possible to drive the motor in this mode. Check your motor datasheet please. 

If in doubt, please start with a lower supply voltage and check motor heating when raising the voltage.

Power supply requirements 

The power supply should be designed in a way, that it supplies the nominal motor voltage at the desired 
maximum motor power. In no case shall the supply value exceed the upper / lower voltage limit. To ensure 
reliable  operation  of  the  unit,  the  power  supply  has  to  have  a  sufficient  output  capacitor  and  the  supply 
cables should have a low  resistance, so that the chopper  operation does not lead to an increased power 
supply  ripple  directly  at  the  unit.  Power  supply  ripple  due  to  the  chopper  operation  should  be  kept  at  a 
maximum of a few 100mV.  
 

Therefore we recommend to 

-

 

keep power supply cables as short as possible 

-

 

use large diameter for power supply cables
