Rating of dc motor

Going for higher voltages will cause insulation breakd. A simple DC motor may be rated by rpm and torque. The power of any LOAD device is the product of its input voltage and its current consumption.

The voltage supplied is the input.

Based on the energy being consumed (work being done) the consumption will vary.

When selecting DC motors , industrial buyers need to identify the key performance specifications, determine .

Another essential criteria of electrical motor power rating is that, during operation of motor , heat is produced and it is inevitable due to .

Consumer products that have horsepower listed are usually rated in peak Hp. So if your motor , on average, draws 1. Also, a given motor draws more current as it delivers more output torque. Thus current ratings are often given when the motor is stalled.

At this point it is drawing the maximum amount of current and applying maximum torque.

A low voltage ( e.g., Volt or less) DC motor may draw from 1mA to several amperes at stall, . The gearing reduces the shaft speed and increases the torque. In order to pick the right size pulley, I need to be able to determine the operating . It is composed of 4stacked laminations 0. The armature has slots and the commutator has 2bars. Motor only consume active power and . If the armature voltage is lowered with the field held constant the current will be proportional to load torque.

If the load requires the same torque at the lower spee the current will not change.

If the motor is self coole the temperature will increase. The service factor is typically in the 1. We further modify these designs for specific applications, washdown, explosion proof, metric mountings and integral DC tachometer. This small electric motor can be used for toys, hobbies, science and technology experiments, robots, automation and many more. It has two electrical contacts in the back . The continuous power rating is a .
