Frequent question: How do I choose a conveyor motor?

How do you select a gearbox and motor for conveyor?

In order to size a gearmotor, we need to identify:

  1. Speed (N) – The speed required to drive the application per its specifications.
  2. TACCEL – The reflected acceleration torque.
  3. TFRICTION – The reflected friction torque.
  4. TBREAKAWAY – The reflected breakaway torque.
  5. TGRAVITY – The reflected gravity torque.

Which motor is best for conveyor belt?

AC induction motors are ideal for conveyor systems that operate continuously in one direction. For conveyor systems where the load must be held in place or for vertical applications, there are a wide range of AC motors with power-off activated electromagnetic brake.

How do you calculate the power required for a conveyor?

Horsepower required for conveyors transporting material on level ground:

  1. 1 hp (English horse power) = 745.7 W = 0.746 kW.
  2. 1 ft (foot) = 0.3048 m = 12 in = 0.3333 yd.

Which DC motor will be preferred for conveyors?

Conveyors need high starting torque initially, and constant torque later. So that, the DC series motor is used in conveyors as it provides very high starting torque, which is practically 5 times the rated torque.

What type of motors are used in conveyor systems?

Motors and Drives for Conveyor Systems

  • Drives.
  • Brushless DC Motors.
  • Integrated Motor Drives.
  • Linear Actuators.
  • PMDC Brush Motors.
  • Stepper Motors.
  • Housed AC Motors.

How do you calculate motor selection?

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.

How do you choose a conveyor belt?

Factors to Consider While Selecting a Conveyor Belt

  1. Weight: The weight of the product is one of the important considerations while selecting an appropriate belt because heavy materials can bend or wrap the belt. …
  2. Size: The size of the product should be the next consideration when you purchase a belt.

How do you calculate torque for conveyor?

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.

How do you control conveyor speed?

Long or heavily loaded conveyors can require very high starting torque. Variable-speed conveyors can overcome this problem by ramping up the speed gradually. Large conveyors in fixed speed operation are often driven by slip-ring motors using extra resistors in the rotor circuit to reduce starting currents.

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 conveyor capacity?

CAPACITY (TPH) = . 03 x Belt Speed (FPM) x material weight (lb. per cu. ft.)

How do you calculate conveyor screw capacity?

The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm.

The Capacity Factor for short (2/3) pitch is 1.50.

Capacity Factors for Special Pitches
Pitch Description Capacity factor
Half Pitch = 1/2 Diameter 2.00
Long Pitch = 1-1/2 Diameters 0.67

Which DC motor is preferred for crane and hoist?

Which DC motor is generally preferred for cranes and hoists? Explanation: DC series motor is used where high starting torque is required, thus in cranes and hoists DC series motor is used widely.

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.
