ELECTROMEN
EM-346 is brushless DC-motor driver with hall sensor feedback. The unit has a mosfet power stage with good efficiency and it meets
also todays EMC requirements. The driver can be used with 120° commutation. This driver has true 4Q power stage, and it makes
possible to use regenerative braking . In this braking method the supply voltage rises, this voltage rising can be controlled with braking
resistor. If uses battery supply then the braking energy can be leaded back to battery and braking resistor will not needed.
The unit has the basic digital command inputs like direction, brake, start/stop, disable and there is analog inputs for speed and
current control. One digitally presetable second speed (speed-2) is possible to activate with digital command input. EM-346 has
two NPN outputs for fault and overcurrent indication use. Some input and output functions can be modified with parameters.
Driver includes overvoltage, undervoltage and overtemperature protections. These fault situations are indicated with fault on-board LED.
Overtemperature and current limit situations can be reset with reset input, reset-timer or by setting analog speed control to value to 0.
There are two control options for speed. Direct control ( open loop ) sets motor voltage in propotion to control voltage as with
a standard DC-motor. Closed loop uses hall sensor feedback for speed control, this mode offers good speed regulation.
Start and stop ramps work in both mode. Speed adjust range, closed loop rpm range and rampse can be set with parameter.
Anolog input are filtered so that there can also use PWM signal for control speed and current.
Setting can be done digitally with EM-236 interface unit or with Emen-Tool lite program installed in PC and EM-268 adapter cable.
Parameters stored into nonvolatile memory of device. This interface unit can also be monitored the current and rpm of motor.
Device can be installed in DIN-rail base and some enclosure options are also available.

W przypadku komponentów elektronicznych umieszczonych w pobliżu obszarów o dużym zasoleniu, wilgoci, narażonych na korozję, kontakt z chemikaliami czy innymi przedmiotami może być niezbędne zastosowanie powłoki konformalnej.
Wyłączniki krańcowe IN73 i MN78 firmy Bernstein idealnie nadają się do małych prądów.
Przetwornik pomiarowy to dla automatyka jeden z ważniejszych elementów w układzie pomiarowym. To właśnie tutaj podłączane są przewody z czujników monitorujących procesy.
Napęd serii WD składa się z niezwykle krótkiego koła jezdnego, zintegrowanej przekładni planetarnej oraz łożyska. W połączeniu z silnikiem BLDC i kontrolerem firmy Nanotec stanowi niezwykle kompaktowe rozwiązanie, które upraszcza konstrukcję, poprzez zmniejszenie ilości wymaganych komponentów, w samobieżnych systemach jezdnych, takich jak roboty usługowe lub pojazdy AGV.
Napędy w pojazdach AGV czy AMR wymagają niezwykle starannego doboru. Źle dobrane komponenty mogą fatalnie przełożyć się na niepowodzenie całej aplikacji i ostatecznie wykluczyć nasz pojazd w dalszych inwestycjach.
PR electronics jako wiodący producent przetworników pomiarowych, stawia na wysokiej jakości rozwiązanie powszechnych problemów w kondycjonowaniu sygnałów.
