Low Voltage Motors
Low voltage motors with standard configurations are always available from stock. Also in stock are three-phase low voltage motors, either as squirrel cage or as slip ring model.
Standard degrees of protection:
IP 55 (fully enclosed)
IP 23 (open construction, open circuit air-cooled, with drip-water protection, suitable for indoor installation only)
|
|
Output ratings up to 50,000kW (70,000HP)
Voltages ranging from 220 to 13,800V
Speed from 3600 to 300rpm
M Line motors are manufactured in different configurations in reference to cooling methods and degree of protection. As a result, a motor configuration can be defined in such a way to better meet operating and environment conditions.
Motor supplied in frame sizes IEC 280 to 450 (NEMA 4400 to 8000) are manufactured in cast iron frames.
Those motors manufactured in frame sizes IEC 500 (NEMA 8800) and larger have their frames built in welded steel plates.
Main advantages in using WEG M Line motors include:
- High efficiency
- Degree of Protection IP23 (WP-I), IP(W)24 (WP-II) or IP(W)55 / IP(W)56 / IP(W)65
- Reduced noise level
- Low and easy maintenance
- Can be built to meet API 541 standards
- Squirrel cage rotor
Slip ring (wound rotor)
- Bearings
Oil lubricated sleeve bearings
Grease or oil lubricated ball or roller bearings
- Interchangeability with existing motors.

AC induction hoist and traction motors offer higher efficiency and smaller size than DC sepex or series wound motors with the same output and thermal performance.
They are without commutator and brushes and require no maintenance. With this type of motor, acceleration and braking torque at higher speeds are not limited by the commutator, which results in shorter stopping distances without the use of a mechanical brake. They also offer longer battery life and more precise control.
F e a t u r e s
• High specific power
• Low performance sensivity to motor temperature (no permanent magnets)
• Small size
• Low noise operation
• Long life maintenance free operation
• Excellent dynamic behavior
• Precise control
• EMC compatible
D e s i g n
• Three phase four pole induction motor
• Aluminium squirrel cage rotor
• Sensorbearing and other separate encoder options available
• UL design available on request
• Available in EE version
• High quality thermal resistant materials
• Free of asbestos, lead cadmium, beryllium and ammonia
