What is AC motor torque?
Torque is defined as the force that gives rise to rotational motion. It is also the result of rotational motion. Torque (t) is equal to force (f) times the radius (r) through which it acts and the angle (Ø) at which the force is applied.

Is Baldor a reliance?
ABB’s Baldor-Reliance® motors are designed to operate reliably no matter how challenging the process or application, and to have low life cycle costs.
Are Baldor motors still made in USA?
“We continue to manufacture in the United States,” says Baldor’s Vice President of Marketing, Randy Breaux, “Our people are very productive and understand that if we don’t take care of our customers, someone else will.
How do you calculate AC motor torque?
- Torque (lb.in) = 63,025 x Power (HP) / Speed (RPM)
- Power (HP) = Torque (lb.in) x Speed (RPM) / 63,025.
- Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)
- Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.
What is rated torque of motor?
Rated Torque This is the torque generated when the motor is continuously producing rated output power at the rated voltage and frequency. It is the torque at rated speed.
How do you read a motor spec?
The RPM listed on the nameplate is the shaft speed for the motor. The speed of the motor is directly related to the frequency of the line voltage and the number of poles in the motor. At 60 Hz, a 4 pole motor will rotate at approximately 1800 RPM (7200/4 poles).
What is Baldor called now?
Baldor Electric Company is now ABB.
Are Baldor motors good?
Best Uses for Baldor Baldor motors are best known for their energy efficiency. Their line of Super-E® motors meets and exceeds the NEMA Premium® efficiency standards. The standard industrial motor sits around 88% efficiency, while the Baldor•Reliance® Super-E® motors are upwards of 94.5% efficient.
How do you choose torque for a motor?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
What is permissible torque?
The permissible torque is the maximum torque that can be used when the motor is running. It is limited by the motor’s rated torque, temperature rise and the strength of the gearhead combined with the motor.
How do I identify my Baldor motor?
12 Serial number (SN) A unique identifier assigned incrementally or sequentially to a motor to identify it specifically. For Baldor-Reliance NEMA motors, the serial number formula is a location-year-month-day-motor code.
What is nominal torque of DC motor?
Nominal (rated) torque is the torque at which the motor can run continuously without overheating. This is not the same as the torque at maximum efficiency. A well designed motor will have its rated torque slightly higher than the torque at max.
Are ABB and Baldor the same?
Is Baldor still in business?
ABB announced Tuesday (Feb. 27) it will drop the Baldor name and unify all properties under the ABB moniker.
Are Marathon motors Good?
Known for their toughness, Marathon motors are best suited for those rugged applications found throughout Canada’s top industries. Their products span a large variety of horsepower and voltage ratings, ensuring a motor for every use across commercial and industrial applications.
Where are Dayton motors made?
Chicago, IL; Niles, IL, U.S.A.
What is maximum torque of motor?
So, when slip s = R2 / X2, the torque will be maximum and this slip is called maximum slip Sm and it is defined as the ratio of rotor resistance to that of rotor reactance. NOTE: At starting S = 1, so the maximum starting torque occur when rotor resistance is equal to rotor reactance.
How do I read my electric motor specs?
What information is on a motor nameplate?
The nameplate includes the based speed given in RPM. Base speed is where the motor develops rated horsepower at rated voltage and frequency. Base speed indicates how fast a fully-loaded output shaft will turn the connected equipment when proper voltage and frequency is applied.
What happened to Baldor?
This business was formerly known as Baldor Electric Company until its company name was merged into ABB on March 1, 2018. ABB Motors and Mechanical Inc. The US business unit, headquartered in Fort Smith, Arkansas, oversees 15 manufacturing locations in 8 states.
