| | | Today, the demands on servo drive systems are more stringent than ever before. The various components of the drive units all complement each other perfectly. Servo motor ranges representan important part of this system. Tailored to various applications, synchronous and asynchronous motors which have been optimised to satisfy the various requirements in terms of dynamic response, accuracy and drive behaviour, are available across a wide torque and power range. Dynamic All servo motors feature a low moment of inertia and a high overload capacity. Continuous temperature measurement using an integrated thermal sensor delivers optimal control response that is predominantly temperature-independent. In combination with the servo inverters, high speed precision, ideal smooth running characteristics and high angular accelerations can be achieved. Precise In combination with the specially designed neodymium iron boron (NdFeB) high-energy magnets, the new SEpT design (Single Element Pole Technology) enables a distortion-free, entirely sinusoidal working field to be generated on MCS synchronous servo motors. This ensures both excellent smooth running characteristics (due to the absence of field distortion) and maximum power density (as almost the entire induced energy is used to generate the working field). This optimised field form also eliminates practically all distorting cogging and detent torques. Long service life The high quality levels demanded of the components in question satisfy the requirements placed on modern drive systems in terms ofoperational reliabilityand service life. A reinforced insulation system with thermal reserve (enamel-insulated wire to temperature class H, for class F use) ensures the long operating life of the winding. The fully-encapsulated stator of the MCS servo motors also ensures the winding is thoroughly protected, even in the event of severe vibration, and allows heat to be dissipated more effectively. This offers an increase in load capacity and a long trouble-free service life. Pretensioned and generously dimensioned roller bearings with high-temperature resistant grease also guarantee a long service life of the bearings. | | Operational reliability The IP54 version of the MCS, MDDKS and MCA series provides a good degree of protection from dust and waterforthe motors. If the drives require even more protection, the MCS, MDDKS and MCA motors are also available with an IP65 enclosure. | | |
| | | CE conformity All Lenze servo motors naturally meet the requirements of the following EC Directives: ► CE conformity with the low voltage directive ► CE conformity according to the EMC directive for a typical drive configuration with inverter Compliance with the EMC directive can be easily assured by using prefabricated system cables. UL certification All servo motors are prepared for use on the American continent. The servo motors in the MCS and MCA series are cURus certified.The servo motors in the MDSKS, MDFKS and MDFQA series are UR certified. (Exception: design with a 205 V brake.) | | |
| | | No compromises in terms of output speed The large ratio range of Lenze gearboxes, combined with the small ratio step of 1.12, allows the required output speed range to be chosen very precisely. The ability to attach the gearboxes directly in the case of the servo motors in the MCS, MDDKS and MCA series produces an extremely compact drive unit with a minimal unit volume. It goes without saying that all servo motors can also be combined with gearboxes in the conventional manner. | | |
