The subsections of this item cover design and specification of an induction motor on a bulk material handling belt conveyor.
Below are the items currently available:
The direction of rotation of the motor depends on the electric connection configuration, a three-phase induction motor can operate at any direction of rotation. The direction of rotation can be reversed by exchanging the position of two of the connecting ...
Electric motors convert electrical energy into mechanical energy. The mechanical output power of the motor is defined as the product of the rated speed and torque. Mechanical power is typically defined as kilowatts (kW) or horsepower (hp) with one watt eq...
The motor terminal box is a box thin in which the leads from the motor are connected to the leads from the power supply. The location of the terminal box is determined by the IEC 60072 standard. The common mounting positions are provided below.

The motor frame is the supporting structure of the assembly; the stator core and the field winding. It acts as a covering, and it provides protection and mechanical strength to all the inner parts of the motor and cooling through fins. The IEC motor fram...
The speed at which an induction motor operates depends on the input power frequency and the number of electrical magnetic poles in the motor. The number of poles is inversely proportional to the speed of the motor. A list of the standard number of poles i...
The International Electrotechnical Commission (IEC) introduced the standards to harmonize efficiency classifications for motors manufactured and sold in the global market. The IEC established methods of determining efficiencies from tests, and also to spe...
A list of common conveyor AC motor application supply voltages is provided below.
Electric motors generate heat because of electrical and mechanical losses. Cooling is necessary to continuously transfer the heat to a cooling medium, such as the air. In AC induction motors, the cooling air is usually circulated internally and externally...
The motor terminal box is a box in which the leads from the motor are connected to the leads from the power supply. The location of the terminal box is determined by the IEC 60072 standard. The common mounting positions are provided below.
The smooth starting of a conveyor belt system is accomplished using torque-control equipment, either mechanical or electrical or a combination of the two. Below is the list of equipment combinations used to ensure a smooth start-up.
