The DC motor requires a power supply that converts the input voltage of 230 volts to a DC voltage of 24 volts (logic voltage) and 40 volts (power voltage).
DC motors are also referred to as EC motors because they are electronically commutated. Compared to AC motors, they offer great advantages in terms of control options and energy efficiency. Additionally, DC motors are able to achieve a wide range of speeds without gear changes:
- i=30 for a belt speed of around 3 to 21 m/min
- i=50 for a belt speed of around 2 to 13 m/min
Either using digital inputs and outputs or CANopen. In connection with a power supply developed in-house by STEIN (see right column), a control system using AS-i is also possible.
Advantages of a DC motor:
- Every operating mode can be controlled electronically (start, stop, speeds, direction of rotation, acceleration and deceleration).
- Greater efficiency.
- No fan or cooling fins (suitable for near clean-room environments).
- SoftMove is possible in combination with the STEIN control system.
