Abb slip-ring modular motors are used in applications requiring high starting torque or low starting current. These motors provide maximum availability, and are especially recommended for heavy load inertia applications like mill drives or situations where network conditions are weak.
ABB’s slip-ring modular motors are available as N-series general purpose motors (type NMK) and A-series engineered motors (types AMK and AML).

N-series general purpose motors combine cost-efficient standardized designs and short lead times with safety, productivity, energy efficiency and reliability. They are targeted at applications where a highly customized motor is not needed.

The pre-engineered N-series complements ABB’s A-series of engineered motors, which are highly customized, fine-tuned to the customer’s precise needs, and offer a high degree of engineering flexibility.
