Table 4-27 Power supply requirements
1) Use the formula below to calculate the required voltage under load.
2) Choose a power supply according to the calculated voltage. Thereby consider:
a)
During braking of the load, the power supply must be capable of buffering the recovered
kinetic energy (for example, in a capacitor).
b) If you are using an electronically stabilized power supply, make sure that the overcurrent pro-
tection circuit is configured inoperative within the operating range.
The formula already takes the following into account:
• Maximum PWM duty cycle of 90%
• Controller’s max. voltage drop of 1 V @ 12 A
KNOWN VALUES:
• Operating torque M [mNm]
• Operating speed n [rpm]
• Nominal motor voltage U
