1. Introduction
Due to its construction, the rotational speed of a 3-phase AC motor is directly dependent on the
number of poles and the frequency of the network. In case of a 3PH 50Hz network and a 2-pole
motor, the nominal speed would be 50 rps * 60 = 3000 rpm.
In case of BLDC motors (brushless dc), the speed is directly dependent on the voltage applied.
3-phase AC motors provide numerous benefits in industry, such as brushless operation, freedom
from wear and tear, favourable capacity/weight ratio, high-speed capability, and much more.
These motors can be used many different application areas, such as milling and grinding
spindles, or with drilling machinery, for example.
The advantages of SFU0303 compared to similar converters:
-
Safe Power Stage Pulse inhibitor, authorized to current regulations EN 954_1 Categorie 3
- Maximum Power in industrial network up to 5kVA
- High efficiency by symmetrical PWM
- Real time vector control for sensorless operation
- Maximum Torque even at lowest rotational speeds
- High possible acceleration rates for short process times. For example 25.000rpm/sec with a
2,2 KW Motor (with robotic applications)
- Pulse-Amplitude (PAM / =Block-Modus ) Control possible because of regulated intermediate
voltage control (on option)
- Very slow rotational speeds (10rpm) possible for reaching tool changer positions.
- Very low current consumption because of real time power control
- Easy Integration into new and existing PLCs because of flexible I/O configuration
- Various interface options: Profibus, RS485, RS232, USB
- Easy reversing the direction of rotation by Software without loss of power.
- Autotuning function for spindle setup.
- Testrun with graphical documentation of voltages and currents of the spindle
- Up to 16 different spindle characteristics can be stored
- Very user-friendly debugging interface for setup control
- Start/Stop Interface for periodical tests or remote control
- Operating panel is detouchable and can be used as remote control together with an
extension cable
- Designed for roughest use in industrial environment
- The housing of SSE is realized without ventilations slots and an outside mounted heatsink.
preventing by this the intrusion of dirt and chips of tooling.
- Very compact case style makes easy cabinet mounting possible
