Nord SK700E-151-340-A Frequency inverter

The Nord SK700E-151-340-A is a highly reliable, microprocessor-controlled frequency inverter module that delivers a power output of 1.5 kW. It utilizes an advanced Sensorless Current Vector Control (ISD) system to maintain high torque and precision motor control across broad frequency spectrums. Featuring an open, modular chassis construction, this compact IP20-rated unit easily integrates customized I/O extensions, technology boxes, and global fieldbus network interfaces directly inside its housing without consuming extra cabinet space.

Q1. What is NORD's core design philosophy for its gear units?

A1: NORD is the global pioneer of the UNICASE design concept introduced in 1981. Unlike traditional split-gear housings, the UNICASE design integrates all bearing seats and sealing surfaces into a single, rigid, one-piece casting. This eliminates joint faces that are prone to oil leakage under heavy loads. It also ensures precise alignment of shafts and gear teeth, reducing internal stress, minimizing noise, and significantly extending the mechanical service life of the drive system.

Q2. How does NORD implement energy efficiency across its motor technologies?

A2: NORD heavily emphasizes sustainable engineering by manufacturing synchronous and asynchronous motors that strictly comply with international efficiency classes (IE3, IE4, and IE5). A key technological highlight is their IE5+ Permanent Magnet Synchronous Motor (PMSM) generation. These motors utilize advanced permanent magnet technology to achieve exceptionally high efficiency—often exceeding the highest standardized IE5 requirements even under partial load and low-speed conditions, which drastically reduces total cost of ownership (TCO).

Q3. What is NORD's approach to decentralized drive architecture?

A3: NORD is a strong proponent of decentralized automation, shifting control intelligence directly from central electrical cabinets down to the field level. Their decentralized frequency inverters and motor starters (such as the NORDAC BASE, FLEX, and LINK series) are designed to be mounted directly onto or near the motor. This modular setup reduces costly control cabinet space, eliminates long shielded motor cables, decreases electromagnetic interference, and allows for highly scalable, plug-and-play installation of large conveyor and logistics systems.
