With the proliferation of VFDs to control motor speed in many applications, using an inverter duty motor designed for use with the drive will protect against premature failure. Inverter Duty motors designed specifically for variable speed control. They are designed to handle the additional heat generated when running at lower speeds. Vector Duty motors typically provide continuous constant torque performance across the entire speed range from zero speed to base speed.

At Wolters Motors & Drives, we offer today’s best inverter duty motors from some of the leading manufacturers in the industry. Some of the top brands we carry include:

• Baldor Industrial Motors: Traditional industrial motors are used for a variety of applications, but there are some uses that call for a little more performance from the motor. That’s where inverter/vector motors come into play. These motors from Baldor are designed to offer constant torque at zero speed. Their standard NEMA-frame motors also perform bypass operations and deliver a 1000:1 speed range.
• WEG Industrial Motors: The three-phase motors available from WEG offer inverter-duty applications. They’re designed with an exclusive WISE insulation system that increases winding dialectic resistance, enabling VFD operation of up to 575V. They also offer lower operation costs by consuming the minimal amount of energy possible.
• Marathon Industrial Motors: The Marathon inverter duty motors available from Wolters Motors & Drives offer a 1000:1 constant toque speed and a patented MAXGUARD insulation system for reduced vibration. Designed for crane, and hoist and winch applications, their inverter duty motors are optimized to operate with all IGBT converters. They’re also performance-matched to all of today’s top brands of PWM drives, ensuring steady use for many years to come.
