Moteurs pour convertisseur (VSD)

Innomotics converter operation motors (VSD motors) are specifically engineered for reliable, efficient operation with frequency converters across wide speed ranges. As part of the Siemens Group, Innomotics brings decades of expertise in designing motors that withstand the unique electrical and thermal stresses of inverter-fed operation, delivering superior performance and extended service life.

The VSD motor portfolio includes both GP (General Purpose) and SD (Severe Duty) variants optimized for variable speed applications. Key design features include reinforced winding insulation systems rated for high dV/dt voltage spikes, insulated bearings to prevent bearing current damage, and advanced cooling configurations that maintain optimal temperatures across the entire speed range.

Whether your application demands constant torque over a wide speed range, field weakening for extended speed operation, or precise dynamic response for process control, Innomotics VSD motors deliver reliable performance. Combined with SINAMICS frequency converters, they form a perfectly matched drive system with integrated diagnostics and energy monitoring capabilities.

All Innomotics VSD motors comply with international IEC standards and are available in multiple frame sizes, voltage ratings, and protection classes. Our engineering team can help you select the optimal motor-drive combination for your specific application requirements, backed by the global Siemens service network.

Frequently Asked Questions — Moteurs pour convertisseur (VSD)

What are converter operation motors (VSD motors)?

Converter operation motors, also known as VSD (Variable Speed Drive) motors, are electric motors specifically designed to operate with frequency converters. They feature reinforced winding insulation, optimized rotor designs, and enhanced cooling systems to handle the electrical stresses and wide speed ranges associated with inverter-fed operation.

Why do I need a VSD-rated motor instead of a standard motor?

Standard motors operated with frequency converters experience additional electrical stress from high-frequency voltage spikes (dV/dt), which can degrade winding insulation over time. VSD-rated motors from Innomotics feature enhanced insulation systems, optimized bearing currents protection, and thermal designs that ensure reliable long-term operation across the entire speed range.

What speed range do Innomotics VSD motors cover?

Innomotics VSD motors are designed for wide speed ranges, typically from 10% to 100% of rated speed with constant torque, and up to 200% of rated speed in constant power mode. Some models support even wider ranges depending on the application requirements and cooling configuration.

Can Innomotics VSD motors be used with any brand of frequency converter?

Yes, Innomotics VSD motors comply with IEC standards and can be operated with frequency converters from any manufacturer. However, combining them with Innomotics SINAMICS drives ensures optimal performance matching, simplified commissioning, and integrated diagnostics through a single engineering environment.

What cooling options are available for VSD motors?

Innomotics VSD motors are available with self-ventilated (IC 411), force-ventilated (IC 416), and water-cooled configurations. Force ventilation is recommended for applications requiring high torque at low speeds, as it maintains cooling performance independent of motor speed.
