Speed feedback for synchronous motors: Speed feedback for induction motors: Tools Drive Technology Drive Technology.
Customer benefits Cabinet units in IP21 or higher degrees of protection All of the drive units have their own connection space Compact dimensions Equipped with radio interference suppression Low harmonics fed back into the line supply, mainly on and pulse versions Almost unlimited motor cable lengths possible inherent to the system High overvoltage strength, e. Output voltage basic fundamental: Safe, reliable and disturbance-free operation using the integrated filter, reactors and contactor s for the travel commands.
IP21, higher degrees of protection optionally available To the top of the page.
LOHER DYNAVERT L PWM Inverters for Lifts – Drive Technology – Siemens
Possible with induction motors up to 1. Depending on the particular requirement, they can be flexibly used for supply voltages extending from V to V. Search Search term s Search.
Transparent operator control and setting using a menu-prompted 4-line plain text display with membrane keypad at the drive inverter — or up to m away in the main control room via RS Skip directly to content. ATEX-certified for motors located in hazardous zones with Accessory kit S, also with very long motor cable length.
Medium Voltage Converters go. Direct forced air cooling, automatic temperature control. Technical data overview Rated input voltage Typ. Up to an elevator power of 30 kW the drive unit can be accommodated in a control cabinet with a depth of mm.
Turn on more accessible mode. Comfortable operation possible — even without speed feedback for asynchronous motors, up to approx. Search Search term s Search. Medium Voltage Converters go. Compact and ready-to-connect unit with integrated EMC filter, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands. Depends on the motor Line supply frequency: This means that from the inherent principle, 4-quadrant operation is possible without requiring any additional measures.
They have a fully controlled B6 bridge circuit on the line side and a B6 inverter circuit on the output side, which utilizes the principle of interphase commutation; this distributes the DC link current from the DC link reactors with a square waveform with frequency f to the motor winding.
Turn off more accessible mode. For regenerative operation, the rectifier on the line-side feeds the regenerated energy back into the line supply. IP20 Ambient temperature, storage: To the top of the page. Low Voltage Converters go. Today, elevator drives are designed either as gearless or as geared solutions.
Selection and Engineering Tools go. Selection and Engineering Tools go. This is the reason that no additional wiring is required. Tools Drive Technology Drive Technology.
LOHER DYNAVERT I Current-Source Inverters
Their equipping means that they can be easily used in all operating environments — even in hospitals and chemical plants. IP21, higher degrees of protection optionally available.
Direct forced air cooling, automatic temperature control To the top of the page. Skip directly to content. Turn on more accessible mode. Customer benefits Loherr and ready-to-connect unit with integrated EMC fynavert, line reactor, braking chopper, braking resistor and a quiet contactor for the travel commands.
Technical data overview Rated input voltage Typ. To the top of the page. Motor cable length shielded or non-shielded: They can control both synchronous as well as induction motors.
Mechanical degree of protection: Low Voltage Converters go. As a consequence, the motor cable length is almost unlimited. The power flows from the line supply to the motor for a motoring load.
