Description

Impel 20.0 HP 6 Pole IE2 960 RPM B5 Flange Mounted 180 Frame 415V Three-Phase Squirrel motor

Full Specifications  :

The 20 HP (15.0 kW) squirrel cage induction motor, configured in a Frame Size 180L, is a robust and high-performance electric motor designed for heavy-duty industrial applications. Engineered with a 6-pole configuration, it operates at a rated speed of 960 rpm and is suitable for operations requiring moderate speed and high torque. The motor supports bidirectional rotation (both CW & CCW), making it versatile for various mechanical and process-driven tasks.

This motor is designed with the IC 411 cooling method, featuring a Totally Enclosed Fan Cooled (TEFC) structure, ensuring excellent heat dissipation and enhanced protection against environmental contaminants. It has a protection degree of IP55, which safeguards the motor against dust ingress and low-pressure water jets from any direction, making it ideal for demanding operating environments such as processing plants, conveyors, compressors, and more.

The motor operates on a 415 V, 50 Hz power supply with a permissible variation of ±10% in voltage and ±5% in frequency. It is built with Class F insulation, capable of withstanding higher thermal loads, and rated for continuous duty (S1), ensuring reliable performance over long operational periods.

With a rated current of 28.0 A, the motor delivers a rated torque of 145 Nm, with a slip of 4.0%. It offers strong starting and overload capabilities, boasting starting current of 700%, breakaway torque of 200%, and breakdown torque of 246% of the rated torque. The service factor of 1.00 indicates it operates within its design limits under normal conditions.

In terms of energy efficiency, the motor is highly efficient across varying loads:

• Efficiency at 100% load: 89.70%
• Efficiency at 75% load: 89.30%
• Efficiency at 50% load: 88.30%

The power factor also improves with load:

• 0.74 at 50% load
• 0.80 at 75% load
• 0.82 at full load

It features high-quality deep groove ball bearings: 6311 ZZ C3 on the drive end and 6310 ZZ C3 on the non-drive end, ensuring smooth rotation and minimal friction. Both ends are protected with V’Ring / oil-seal arrangements, enhancing durability and extending bearing life by preventing the ingress of contaminants.

This motor is available in multiple mounting configurations—B3 (foot) offering flexibility for integration into different mechanical setups. With an approximate weight of 160 kg, it balances sturdiness with installability.

In summary, this 20 HP, 6-pole, 180L frame induction motor is a highly efficient, reliable, and durable choice for medium-speed, high-torque industrial operations, offering excellent electrical and mechanical performance for long-term service.
