DC motors series MM

Product catalog summary
General Features
The MM series DC motors are noted for their compact and robust design, offering a high power-to-size ratio. They are ideal for industrial applications requiring constant torque speed regulation, with power ranging from 1 kW to 150 kW at 2300 rpm. The motors are available in eight shaft heights, with sizes 80, 90, and 102 having two poles, and larger sizes featuring four poles and compensator windings.

Construction Features
The stator is constructed from soft iron sheets for mechanical strength, with copper windings insulated by NOMEX. The rotor is made from magnetic sheets and includes numerous blades to ensure reliable performance and minimal maintenance.

Standards
The motors adhere to Italian Standard CEI EN 60034-1 and IEC 34.1, meeting major European standards, and are available in various forms as per IEC 34-7 recommendations.

Vibrations
Dynamic balancing is standard for reduced vibration class R, with class S available upon request. Vibration limits are specified according to ISO standards.

Electrical Connections
Motors feature an IP 44 connection box with multiple mounting options. Grounding is provided by two screws, and terminal markings are included for different windings.

Bearings
Standard models use self-lubricating ball-bearings, with roller bearings available for high radial loads. A formula is provided for verifying radial load.

Protection and Ventilation
Standard models include a fan on the connector side, with other ventilation systems available upon request.

Painting and Insulation
Motors are painted with an epoxy primer and available in standard colors. They are designed with insulation class F, using materials mostly in class H for enhanced reliability.

Excitation
Standard excitation is independent, with voltages of 110, 220, and 330 V. Excitation voltage increases by about 35% from cold to hot conditions.

Power Tables
Power ratings are provided for each motor based on speed and armature voltage, under conditions like continuous service and ambient temperature.
Specifications
Specifications detail power output in relation to ambient temperature and altitude, with insulation class F allowing a maximum overtemperature of 105°C for continuous duty. Materials are selected for class H reliability.

Painting and Pretreatment
Motors undergo pretreatment and are painted with an epoxy bicomponent primer. Standard colors include Grey (Ral 7031), Green (Ral 6011), and Lustreless Black, with other colors available upon request.

Field and Excitation
Motors are manufactured with independent excitation, standardized at 110, 220, and 330 V, with excitation voltage increasing by approximately 35% from cold to hot.

Power Tables
Tables provide working power for each motor type, considering speed and armature voltage, with conditions including a maximum ambient temperature of 40°C and altitude of 1000 m.

Testing and Overloads
Motors undergo tests for insulation, electrical continuity, resistance, and more, with overload tests up to 1.6 times the nominal torque.

Accessories
Optional accessories include tachogenerators, encoders, centrifugal relays, and anti-condensation heaters.

Special Arrangements
Customizations are available based on customer requests, such as special dimensions or shaft designs.

Production Program
The company produces DC motors, servomotors, brushless servomotors, tachogenerators, and asynchronous vectorial motors.
