How do you choose a motor?
A constant or variable torque and horsepower will be required for the industrial motor depending on the type of load the motor is driving. 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.
How do I check conveyor speed?
Measure the circumference of the rollers in the conveyor , calculate revolutions per minute and then multiply these two figures together to determine conveyor belt speed.
How do you calculate the TPH of a conveyor?
CAPACITY (TPH) = . 03 x Belt Speed (FPM) x material weight (lb. per cu. ft.)
How much weight can a conveyor belt hold?
Loads up to 200 pounds.
What will happen if DC motor is used without starter?
What will happen if DC motor is used without starter? Explanation: It would cause intolerably heavy sparking at the brushes which may destroy the commutator and brush-gear. … Explanation: In shunt and compound motors starting the shunt field should be switched on with full starting resistance in armature circuit.
How do you change the direction of a DC motor?
The direction of rotation of DC series motor may be reversed by changing the polarity of either field or the armature winding.
How do you size a motor?
Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.
What is torque in electric motor?
Torque: The torque output of a motor is the amount of rotational force that the motor develops. The torque of a small electric motor is commonly measured in either inch pounds (in-lbs), Newton meters (N-m) or other directly converted units of measure.
