Question: How Do You Select A Motor Based On Torque?

What is rated torque of motor?

Rated torque is the maximum continuous torque available at the design speed that allows the motor to do the work without overheating.

Starting torque is the torque the motor delivers at zero speed.



It is also called the stall torque..

How do you make an electric motor more powerful?

We can increase the turning force (or torque) that the motor can create in three ways: either we can have a more powerful permanent magnet, or we can increase the electric current flowing through the wire, or we can make the coil so it has many “turns” (loops) of very thin wire instead of one “turn” of thick wire.

Which type of motor has high starting torque?

DC motorDC motor has high starting torque.In a series motor the same current flows through the armature and the field winding.

What is the fastest electric motor?

The British appliance manufacturer Dyson claims to have developed the world’s fastest, most efficient motor for domestic appliances. The Dyson Digital Motor (DDM) v2 is a single-phase brushless DC motor, which operates at speeds up to 104,000 rpm with a claimed efficiency of 84%.

How can a motor be made more efficient?

Energy efficient induction motors Induction motors can be made more energy efficient by: using copper windings in the stator coils. using copper bars in the rotor. machining all moving parts to a high precision.

What is the most powerful electric motor for go karts?

Mophorn 1800 W Electric MotorThe Mophorn 1800 W Electric Motor is the best electric motor for go-karts in our list, due to its power, superb build quality and it’s high performance-to-cost ratio. As the name already gives away, this electric motor has a power output of 1,800 watts, which is powerful enough for any type of go-kart.

How much torque does a 1 hp motor have?

The 3600 RPM, 1HP motor produces 1.5 ft. lbs. of torque at 3600 RPM. So if your 1HP pump was operating at 1800 RPM, the 1800 RPM motor would be producing 3 ft.

What is the fastest electric go kart?

Daymak C5 BlastThe world’s fastest go-kart is the all-electric Daymak C5 Blast and it can zoom from 0 to 60 mph in just 1.5 seconds.

How much torque is required to move a car?

Overall transmission (and power-train) efficiency of the modern electric vehicles is within 59 .. 62 %. The answer to your question is 43.2 Nm of Torque required that can be obtained with the transmission ratio value of 15.

How do you specify a motor?

The first key thing you should know is power, measured in either horsepower for NEMA standardized machines, or kilowatts typically for IEC standardized machines. Horsepower (HP) measures the amount of power a motor can give defined by torque multiplied by speed divided by 5250 feet pounds.

How do you select a motor according to load?

The size of the load, the required speed, and acceleration/deceleration—particularly if it’s fast and/or frequent—will define the torque and horsepower that is required. Requirements for controlling motor speed and position also need to be considered.

What is the strongest electric motor?

high temperature superconductorA high temperature superconductor (HTS) developed by Northrop Grumman Corporation and tested by the U.S. Navy holds this title. It is the world’s first 36.5 megawatt (49,000 horsepower) HTS ship propulsion motor.

How do you size a motor?

Motor sizing made simpleMaximum number of starts for selected motorsHPTWO POLE (3,600 rpm)FOUR POLE (1,800 rpm)106.246204.855503.4724 more rows

How can you tell how much weight a motor can move?

The formula that relates mass, force and acceleration is: F = m*a , where F is the force, m is the mass and a is the acceleration. So a = F/m would be 14.715 kg*m/s² divided by 2 kg and therefore: ~7.358 m/s².

How is rated torque calculated?

Torque ( = 63,025 x Power (HP) / Speed (RPM)Power (HP) = Torque ( 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.

Does lower KV mean more torque?

Torque is determined by the number of winds on the armature and the strength of the magnets. A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop.

Can electric motors get weak?

Yes, electric motors can get weaker over time. Bearings wear out and electric insulation breaks down and can start developing shorts in the winding’s.

How do you make a motor faster?

One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.

What is pull out torque?

Pull-out torque is the maximum torque that can be delivered without losing steps. It reaches its maximum at the lowest frequency or speed, and decreases as frequency increases. … Pull-in torque is the maximum torque at which a motor can start rotating at a given frequency.

How do we calculate torque?

A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.
