Variable Speed Drives
NORD Variable Speed Drives (VSDs) are advanced, energy-efficient control solutions designed to optimize the performance of industrial drive systems, covering both electronic frequency inverters and mechanical variable speed variants. As a core component of modern industrial automation, these drives enable precise speed regulation, torque control, and energy conservation, seamlessly integrating with NORD’s gear motors to deliver tailored drive solutions for diverse applications.
The electronic VSD series, spanning 0.25kW to 160kW, features a modular design with protection ratings ranging from IP20 (for control cabinets) to IP69K (for hygienic, wash-down environments like food processing). Equipped with built-in safety functions such as STO (Safe Torque Off) and SLS (Safe Limited Speed), they comply with international safety standards, minimizing operational risks. These inverters support multiple control modes—including V/f, vector, and servo control—ensuring smooth operation even at low speeds, while energy-saving algorithms reduce power consumption by up to 30% compared to fixed-speed systems.
Mechanical variable speed drives, complementary to electronic variants, are ideal for scenarios where electrical control is limited or cost-sensitive. They utilize friction or pulley-based mechanisms to adjust speed without relying on electronics, offering robust performance in harsh environments with dust, vibration, or extreme temperatures. With simple structure and low maintenance requirements, they suit light to medium-duty applications such as small conveyors and auxiliary machinery.
All NORD VSDs boast easy integration with existing drive systems, supporting communication protocols like Profinet, Modbus, and Ethernet/IP for centralized monitoring and control. They feature user-friendly interfaces for quick parameter configuration, and modular accessories—such as braking resistors and filters—enhance adaptability. Widely applied in conveyors, packaging, mining, and food processing, these drives balance reliability, efficiency, and safety, reducing operational costs and improving process stability for industrial users.
NORD Variable Speed Drives (VSD) Series Specifications
Note: NORD Variable Speed Drives include cabinet-mounted and decentralized (motor/wall-mount) types, supporting IE3–IE5+ asynchronous/synchronous motors, IP20–IP66 protection, and multi-protocol communication (PROFINET, EtherNet/IP, Modbus TCP). Weights are for standard units (excluding external options like brake resistors).
