APPENDIX I

CM CONVEYOR MOTOR

Typical nameplate data for the conveyor motor of a CM can be seen in Table I-1. The

conveyor motor measured at all the sections was a 37 kW induction motor with a full

load current rating of 30 A

I.1 LOAD PROFILE

The next section focuses on the load profiles of the conveyor motor. Each graph

shows the line voltage and the voltage limits, the load current and full load current

capacity of the conveyor motor. The morning shifts and afternoon shifts are separated

as well as the measurements made at the different sections.

I.2 HISTOGRAM

The next section focuses on the frequency with which a CMs conveyor motor

consumed a certain load power and current. The graphs show the number of times a

certain power or current has been consumed. The tables give data about the tonnes

produced during the shift and the percentage time of the shift that the motors were

producing. The time that the motors have been over loaded or loaded within the full

load rating of the motor is given as a percentage of the actual producing time. The

morning shifts and afternoon shifts are separated as well as the measurements made

at the different sections.

I.3 THERMAL CAPACITY

The next section focuses on the temperature of the windings of the conveyor motor.

Each graph shows the temperature of the motor, the load current and rated full load

current of the motor. The morning shifts and afternoon shifts are separated as well as

the measurements made at the different sections. The thermal time constant is

45 minutes.
