Asynchronous electric motors (AC)

Winding

Metalrota AC electric motors are designed with specific winding types to obtain high efficiency at low, medium, and high speeds and optimize motor performance.

Low speed and high starting torque to achieve movement precision

• Low speed winding designed to maximize the starting torque.
• Thicker wires and tighter windings to generate greater starting force at low speeds.
• Used when movement precision is required, such as robotics and machine tools.

High speed for machine transfer

• Winding at high speed designed to maximize rotational speed.
• Thinner wires and less tight windings to reduce electric resistance and allow higher speeds.
• Suitable where fast machine transfer is crucial, such as transport systems, electric cars, and go-karts.

Medium speed for a balanced ratio between starting torque and transfer speed

• Used when a compromise between precision movement and transfer speed is necessary.

Insulation

We manufacture Class H insulation alternating current electric motors. We use high quality materials to ensure excellent thermal and mechanical performances and to ensure a reliable functioning even under high thermal stress.

• We use Class H Superior insulated wire to achieve thermal resistance up to 210°C.
• The motor stator undergoes a surface treatment with epoxy paints and resins. This procedure protects the windings, increases overall motor stiffness and thermal resistance.
• Our AC motors, except for some specific designs, are equipped with phonic wheel speed sensors. These sensors allow rotational speed measuring and are designed to withstand high temperatures. Their simplified design contributes to easier practical use.

Equipment

Metalrota motors can be equipped with electromagnetic brakes from 5Nm to 100Nm.

Level of protection

We supply alternating current motors with protection IP69K.

AC motors are designed to offer maximum flexibility of use in high-speed light traction systems but also for the lifting heavy loads. The motor maintains its reliability and resistance even under extreme working conditions.

They are ideal for powering battery-powered vehicles. They are available in a full range of options in terms of tension and rated power:

• Tension: 24V to 96V
• Rated power: 300W to 50kW

With this targeted design, we assure optimal performance and energy efficiency in electric vehicles for industrial, agricultural, construction, racing handling but also electric and naval mobility.
