Matched Performance™

Matched Performance™ is Baldor’s solution to the concern, “what kind of constant torque and constant

horsepower speed range will I get with this inverter”? And, “what happens if I use a fan cooled motor, an open

drip proof motor or a blower cooled motor, etc.”? Baldor has gone beyond the (2:1, 6:1, 10:1) ratio type

answers and has documented actual laboratory dynamometer testing.

At the heart of these tests is the continuous operating constant torque range. This range of values show how

much torque can be continuously generated without exceeding a Class F temperature rise. This holds true even

with the Class H insulated inverter and vector motors.

The horsepower curve is simply the horsepower representation of the constant torque test.

Peak torque is the maximum amount of torque the Series 15H inverter and the specified motor can produce.

The limit may be breakdown torque of the motor or it may be the control’s current limit. This torque can be used

for momentary overloads and/or for acceleration/deceleration.

Each test is performed by Baldor’s own testing laboratory using state-of-the-art dynamometers, thermocouples

and digital power measuring equipment. A typical matched performance test requires 2 - 4 days of continuous

testing. This painstaking effort is another example of Baldor’s commitment to the drives business and to making

our products easy to use.
