The dynamic, high-precision solution for heavy external l

The lowest possible ratio of load moment of inertia to motor moment of inertia is key for transporting heavy loads from A to B at high speed and with great precision. That's why CM3C.. series servomotors benefit from increased inertia. These servomotors are therefore particularly suited to all automation, handling and transport applications with a correspondingly high load moment of inertia. With their four sizes – 63, 71, 80 and 100 – they can cover standstill torques from 2.7 to 40 Nm.

The servomotors are also exceptionally small and have a space-saving design. What's more, the option of mounting the motor directly on the gear units (direct motor mounting) eliminates the need for adapters and couplings. The multi-stage surface protection concept and smooth surfaces (hygiene-friendly design) make the medium-inertia servomotors particularly robust and dirt repellent. In addition, the rotors, which are equipped with permanent magnets, deliver a very high level of efficiency, thus ensuring exceptionally energy-efficient operation.

Flexibility and reliability are also key features of the brakes that are available for the servomotors. Alongside the 24 V holding brake typically used for servomotors, users also have the option of a brake with increased working capacity. Thanks to this equipment, the synchronous motors can even handle applications where emergency braking is needed. Requirements of this kind are typical in machine automation, handling gantries and travel unit drives.

Thanks to our modular system, the highly flexible CM3C.. series servomotors can be adapted to meet specific needs. At the same time, single-cable technology means they can be installed quickly and integrated intelligently into state-of-the-art Industry 4.0 concepts.

Ohne Getriebe nur die halbe Lösung?

Only half the solution without a gear unit? Not with SEW‑EURODRIVE's modular system! You can opt to combine the CM3C.. series servomotor with a helical, parallel-shaft helical, helical-worm, helical-bevel or SPIROPLAN® gear unit, or with a servo planetary gear unit from the PxG series.

is possible thanks to the MOVILINK® DDI digital interface. It's all based on single-cable technology. In fact, motors and inverters from the MOVI‑C® modular automation system require just one hybrid cable for power supply and data transfer. The hybrid cable supplies the motor with power and MOVILINK® DDI, a digital encoder, transfers all necessary power, brake and diagnostic data between inverter and motor. This saves you both time and money during installation and startup.

The digital motor and data integration works with synchronous motors, asynchronous motors and decentralized drive technology.

Functional safety overview

  • You can also request motors from the CM3C.. series with a safety brake and safety encoder. These can be integrated into the servomotor individually or in combination.
  • The following safety functions are possible with the safety brake:
    • SBA (Safe Brake Actuation)
    • SBH (Safe Brake Hold)
  • Using safety encoders, safety functions relating to rotational speed, direction of rotation, standstill and relative position are possible, such as SS1, SS2, SOS, SLA, SLS, SDI and SLI to IEC 61800‑5-2.
  • Degree of protection: Standard IP54 to EN 60529
  • Ambient temperature: -30 °C to +60 °C (depending on the execution)
  • Sustainability & excellent energy-saving potential:
    • Drive system efficiency to IEC 61800-9-2 (Power Drive System): The highest defined efficiency class IES2 to IEC 61800-9-2 for the system combining motor and electronics
    • Motor efficiency to IEC 60034: Complies with efficiency class IE3 to IEC TS 60034-30-2

Save time and money

and are impressively compact.

The electromechanical components and the drive electronics both benefit from an extremely compact design.

Further complementary features such as direct motor mounting on the gear unit, high torque density and less installation work between hardware components thanks to single-cable technology mean this combination is highly recommended if your focus is on saving time and money.

Flexible & energy efficient

during planning, startup and production.

The new CM3C.. series of synchronous motors achieves energy efficiency class IE5 – an advantage over asynchronous motors.

Only when combined with further motor features such as direct mounting on any gear unit, wide-ranging options and accessories, hygienic design credentials and a cable length of 200 m between motor and inverter, however, does this create a truly flexible and energy-efficient solution.

Functional safety & reliable availability

that extends worldwide.

You can also request the motors from the CM3C.. series with a safety brake and safety encoder – to make protection against personal injury as easy as possible in your system, for example. Used individually or in combination, the functionally safe options contribute to a safe concept.

The modular system also means you are dealing with just one supplier, who delivers worldwide and ensures both short delivery times and long-term product availability.
