Brushless DC-motor with integrated controller
The micro annular gear pump mzr-7245 is driven by electronically commutated,
brushless motors with integrated control. The control unit is composed of a
16-bit microcontroller and power electronics. It enables to adjust both speed
and position of the motor. The motor is highly dynamic and suitable for dosing
tasks performed by the micro annular gear pump. CDs or diskettes containing
software running under Windows
®
which permits to set the parameters, as well
as to program and control the pump are included in the package. The package
contains also a user-friendly terminal box and a null-modem cable for an easy
connection to the serial port of a PC.
