Zero rpm at the drive does not exclude the presence of a holding torque on the shaft of the motor due to load in some circumstances. The motor current will be a reflection of the torque presented at the shaft.
In dc shunt motor,base speed is 500 rpm and its field current is 17A, top speed is 1200 rpm and field current is 5.6 A.But 600 rpm it has reduced by 10A It is normal? How
Materials for producing 2900 rpm motor is less than 1450 rpm one
To calculate horsepower you need the car's torque numbers. To find the horsepower, the formula HP=(RPM*T)/5252. The "HP" stands for "horse power", the "T" in the formula stands for "torque " and RPM stands for the RPM values. To calculate the horse power of an electric motor, you use the formula HP= (V*l*eff)/746. V=voltage, l=amps, and eff= efficiency.
RPM stands for revolutions per minute. This is calculated for different devices and can indicate how fast something is going. For a DC motor, the RPM is calculated by how many times the motor turns.
The torque produced by a 3 horsepower (hp) motor can be calculated using the formula: Torque (T) = (Horsepower × 5252) / RPM, where RPM is the motor's speed in revolutions per minute. For example, at 1800 RPM, a 3 hp motor would produce approximately 8.5 lb-ft of torque. However, the actual torque will vary depending on the motor's speed and design specifications.
The torque of a 3 hp (horsepower) electrical motor operating at 1440 RPM (revolutions per minute) can be calculated using the formula: Torque (in lb-ft) = (HP × 5252) / RPM. For a 3 hp motor at 1440 RPM, the torque would be approximately 10.87 lb-ft. This value may vary slightly based on motor efficiency and design specifics.
Zero rpm at the drive does not exclude the presence of a holding torque on the shaft of the motor due to load in some circumstances. The motor current will be a reflection of the torque presented at the shaft.
Multiply the foot pounds of torque by the rpm.
Horsepower (hp) and revolutions per minute (rpm) are related but not directly convertible without additional information, such as the torque of the motor. Specifically, 1 horsepower is equivalent to 5252 foot-pounds per minute when torque is expressed in foot-pounds. To find the rpm for a 2 hp motor, you would need to know the torque; the formula is: hp = (torque in lb-ft × rpm) / 5252. Thus, without the torque value, you cannot directly calculate rpm from horsepower.

How much torque? I don't know. Should it have torque? Always. I have a motor that can spin close to 10'000 RPM, but I can stop it with my finger because it has very low torque. A good way to remember this is, the faster it spins, the lower the torque. You can increase the torque by using a gear chain to gear-up, trading RPM for torque. Gearing Down is the reverse.
In dc shunt motor,base speed is 500 rpm and its field current is 17A, top speed is 1200 rpm and field current is 5.6 A.But 600 rpm it has reduced by 10A It is normal? How
No. With the values given the motor will run at 1500 RPM. RPM = Hz x 60 x 2/# of poles. The only way the motor can be run at that speed is by using a VFD as its source of power.
from power= torque*angular speed u can calculate torque and from torque u can find the force if the radius is known.
