What is medium voltage motors?
Medium voltage (MV) motors are defined as asynchronous and synchronous AC induction requiring voltages in excess of 1kV. These motors can be connected directly to a local power grid or through an AC drive.
What is the low voltage and high voltage?
Definition
| IEC voltage range | AC RMS voltage (V) | DC voltage (V) |
|---|---|---|
| High voltage | > 1 000 | > 1 500 |
| Low voltage | 50 to 1 000 | 120 to 1 500 |
| Extra-low voltage | < 50 | < 120 |
What is Low Medium high and Extra high voltage?
Voltage levels have been defined and classified by various National and International Standards as also by certain electric power utility companies. -Low Voltage: Not exceeding 250 V. -Medium Voltage: Not exceeding 650 V. -High Voltage: Not exceeding 33000 V.
What are low voltage motors?
In this context, low voltage refers to motors that operate at voltages less than 1 000 V and produce a maximum power of 1 000 kW. The designation IEC means that the motors conform to standards developed by the International Electrotechnical Commission.
What is the difference between Low Medium and High Voltage?
There can be different ideas about what qualifies as a low, medium or high voltage motor. “Some people consider anything above 1000 V as high voltage. The limits are clearly defined, however, in the IEC 60038 standard: low voltage is up to 1000 V, medium voltage is from 1000 V to 35 kV, and high voltage is over 35 kV.
What is Medium and high voltage?
What does high and low voltage do to a motor?
Both high and low voltages can cause premature motor failure, as will voltage imbalance. Thus, when voltage gets low, the current must increase to provide the same amount of power. An increase in current is a danger to the motor only if that current exceeds the motor’s nameplate current rating.
What is high voltage motors?
There can be different ideas about what qualifies as a low, medium or high voltage motor. The limits are clearly defined, however, in the IEC 60038 standard: low voltage is up to 1000 V, medium voltage is from 1000 V to 35 kV, and high voltage is over 35 kV.
What’s the difference between a low and high voltage motor?

What are the different voltages of Hoyer Motors?
In 2018, Hoyer will be expanding its product series with a range of medium voltage motors with voltages ranging from 3 kV to 11 kV, which are well-suited for heavy loads. Hoyer’s technical manager, Bjarne Nør, provides an introduction to medium and high voltage motors.
What’s the difference between medium and high voltage?
“Some people consider anything above 1000 V as high voltage. The limits are clearly defined, however, in the IEC 60038 standard: low voltage is up to 1000 V, medium voltage is from 1000 V to 35 kV, and high voltage is over 35 kV. The motors in our new product series are thus all placed in the medium voltage category,” says Bjarne Nør.
What’s the life of a medium voltage motor?
“While a low voltage motor will only be tested for thermal lifetime, our medium voltage motors are tested for both electric and thermal lifetimes. We have documentation on all our motors for a minimum lifetime of 20,000 hours.
