For conveyor belt applications Oriental Motor offers a wide range options. For fixed or constant speed applications, AC motors & gear motors are well suited. For applications where speed control, higher speeds or maximum torque in a small area may be needed, the AC & brushless DC motor speed control systems can be used.
Protecting a motor from destruction and controlling a process are completely different requirements. If a conveyor jams, the current at the motor leads will climb immediately, and the knowledge that this has occurred can keep the damage to a minimum.

For example, if a current draw of 3.5 amps per motor at the time of installation is set as a standard, a subsequent increase to 4.7 amps would be an indication of friction buildup. Stampers can determine friction increase by attaching an ammeter to the conveyor's drive motor to measure current draw.
