BALDOR

BALDOR

Baldor was founded in 1920 and is headquartered in Fort Smith, Arkansas, USA. Its main products are industrial motors, power transmission products, drive products and generators. On February 1, 2007, the former Rockwell Automation Power System Co., Ltd. of AB was acquired. Formally joined ABB Group in December 2010.

At present, Baldor has three brands:

BALDOR: mainly small and medium-sized, low-voltage motors, variable frequency drives, and servos;

RELIANCE: mainly large, medium and high voltage motors (above 400HP);

DODGE: To CST, reducer, bearing, coupling and other mechanical products.


High-speed motor:

RPMAC motor is a three-phase AC motor specially designed for variable frequency speed regulation applications. The motor power ranges from 0.011kW to 12,000 kW. It can output a constant torque range of 1000:1 and a constant power range of 10:1, with small size and low moment of inertia. , The corresponding speed is fast, and it can be 3 frame sizes smaller than traditional motors, which is especially suitable for application on test bench equipment. Features are as follows:


1. Slender precision dynamic balance rotor --- small moment of inertia, easy to reach high speed

2. H-class insulation optimized pole number design---providing greater acceleration torque and overload capacity

3. Laminated machine base design-small machine base

4. 0-speed constant torque output

5. High speed bearing, low noise design

6. Improved mechanical characteristics, foot mounting method, shorter distance from foot to bearing;

7. Higher surface finish, better shock resistance and stability;

8. Increased mechanical strength, higher resonance speed, suitable for high speed;

9. Fully integrated structure, inorganic shell design, higher power density, higher space utilization.
