Thickened Integrated Cast Iron Frame
The whole body is integrally cast with thickened cast iron, featuring sufficient wall thickness, strong rigidity, impact resistance and high-frequency vibration resistance, suitable for harsh high-impact working conditions such as mines and heavy stamping.
Large-size 160L Standard High-power Frame
Dedicated large 160L frame with ample internal space for iron core and winding layout, matched with 20hp high power output and abundant heat dissipation margin.
Class F Heat-resistant Insulated Windings
Stator wound with thickened Class F enameled wire, with maximum temperature resistance of 155℃. The oil-proof and anti-aging insulation layer avoids breakdown and short circuit under frequent start-stop and variable frequency speed regulation.
7×24h Continuous Heavy-duty Operation
The heavy cast iron frame is anti-deformation with abundant heat dissipation capacity, enabling stable full-load operation all day long, perfect for large crushers, heavy hoists and industrial agitators.
Outstanding Vibration & Noise Reduction
Cast iron material effectively absorbs operating resonance, cuts overall running noise and reduces wear of matched frames, couplings and gear reducers to extend the service life of the whole transmission system.
Strong Adaptability to Heavy Industrial Environments
The full cast iron housing is dust-proof, splash-proof and mechanically corrosion-resistant, supporting long-term operation in dusty, humid workshops with metal scraps without extra protective covers.

10hp three phase motor |
Q:What is the equivalent kW and standard frame size of the 20hp cast iron three-phase motor?
A:20hp is approximately equal to 15kW, matched with standard 160L cast iron frame, customized enlarged frame is available upon request.
Q:What is the difference between Class F and Class H insulation?
A:Class F withstands up to 155℃, with cost performance for most industrial VFD and heavy-duty applications; Class H can resist 180℃, which is applied to extreme long-time high-temperature environments with higher cost.
Q:Does this 20hp cast iron motor support multiple mounting types including B3/B5/B14?
A:Yes, full mounting standards B3, B5, B14, B35, B34 are all customizable, horizontal, vertical and composite flange installation are all available.
