Quantum® LMV

Product catalog summary

Overview: The Quantum® LMV series of induction motors are designed for reliability and efficiency, addressing key factors that can reduce motor lifespan such as heat, stress, vibration, and contamination. These motors are suitable for both low and medium voltage applications, with frame sizes and power ratings specified for different voltage and frequency requirements.

Specifications: The motors comply with NEMA, IEC, IEEE 841, CSA, API 547, and 541 Division 2 Zone 2 AEx nA standards. They are available in NEMA 500 Frame up to 800 HP and IEC 315 Frame up to 600 kW, with voltage options ranging from 230V to 6900V and pole configurations from 2 to 12.

Design Features: The Quantum LMV motors feature a unique internal frame air circuit with patented D-Ducts and trapezoidal rotor vents for enhanced airflow and cooling. They offer flexibility in frame size selection and include options for self-aligning spherically seated sleeve bearings, ball bearings, and roller bearings for severe applications.

Performance and Reliability: These motors are designed for inverter duty reliability with optional insulated bearings and drive end shaft grounding rings to minimize harmful shaft voltages. They are built with a stiff frame and solid class 30 cast iron feet for low vibration and increased power capacity, suitable for extreme temperature environments from -400°C to 400°C.

Construction and Materials: The motors use an epoxy solvent-less resin vacuum pressure impregnation (VPI) process for superior insulation. Multiple oversized vents ensure low temperature rise, and the rotor and internal fan are shrink-fit onto the shaft, meeting API specifications. Standard construction uses cast aluminum, with an option for fabricated copper bars.

Product Range: The Quantum LMV series includes a wide range of standard motors with pre-engineered NEMA ratings for reduced cycle times and cost savings. Models are available for severe duty and IEEE 841 features across various voltage and RPM configurations.

What makes Quantum better? Unique Design Inverter Duty Reliability Superior Bearings An internal frame air circuit with patented frame D-Ducts and trapezoidal rotor vents dramatically increases airflow for a cooler operating motor. This gives more flexibility in choosing frame sizes. Optional Insulated bearings and drive end shaft grounding ring are optional. This minimizes the impact of harmful shaft voltages. A separate blower is available for constant torque applications. Available self-aligning spherically seated sleeve bearings allow the motor to adapt to the best position for the load....
