What is a medium voltage motor?
What is a medium voltage motor?
Operating voltages from 1100 V to 7000 V are considered medium voltage. However, medium-voltage motors for industrial plants are typically requested for voltages from 3000 V or 3300 V and higher, as the two reference projects below show. All motors with over 10000 V are considered high-voltage motors in everyday usage.
What is the specification of induction motor?

What is the limit of medium 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 IEC standard for motor?
In short: the International Electrotechnical Commission (IEC) standards are the uniform standards indicating the efficiency classes for electric motors. In 1999, the European Commission established different efficiency classes for electric motors.
Where is medium voltage used?
Medium-voltage cables are commonly used in mobile substation equipment, for distribution of power in industrial settings and in mining to supply power to drills, shovels, haulers, etc., said David Sedivy, Senior Product Manager at TPC Wire & Cable Corp.
Is 4160 medium voltage?
Motors rated 200 HP and above are often wound for Medium Voltage (2300VAC or 4160 VAC) instead of Low Voltage (480 VAC to 600 VAC).
What are the specifications of a motor?
Motor specifications
- Nameplate.
- Voltage and amps.
- Horsepower and kilowatts.
- Base speed.
- Service factor.
- Insulation classes.
- Motor design.
- Locked rotor code letters.
Can a 400V 50hz motor run on 480V 60Hz?
Electrically, the motor will work fine. The ratio of Voltage and Frequency is exactly the same (400/50 = 8.0, 480/60 = 8.0), so the motor will work at 480V 60Hz and provide it’s full rated torque at nameplate FLA without issue.
What is medium voltage according to IE Rule 28?
-Medium Voltage: Not exceeding 650 V. -High Voltage: Not exceeding 33000 V. -Extra High Voltage: Exceeding 33000 V.
What is the difference between IEC and NEMA motors?
NEMA caters to large-sized devices in North American Markets only. IEC ratings are for more compact devices in the global market. IEC ratings react faster to overloads while NEMA ratings withstand short circuits. IEC devices are safe to the user, while NEMA devices require safety covers.
