A leading global manufacturer of electrical and mechanical drives, motion control and automation technologies, Lenze Americas has launched a series of MCM synchronous servo motors that delivers intermediate-level dynamic performance. Scalable, modular Lenze MCM motors are easy to control and optimized for a range of positioning tasks, including robotics, packaging equipment and handling systems.
"Designed with an optimal torque and inertial mass ratio, our MCM servo motors give customers the precision they need in a compact and simple solution," said Doug Burns, director of sales and marketing, Lenze. "MCM motors work in perfect harmony with Lenze inverters in positioning, return and any recurring motion sequences in the medium dynamic range."
Modular MCM motors feature IP65-rated protection class housings with easily cleaned surfaces for food processing and other applications. Equipped with a robust resolver feedback system as a standard feature, the motors can be optionally supplied with multi-turn, sine-cosine encoders for high precision. SpeedTec connections with rotary connector boxes simplify and expedite installation, maintenance and replacement.
The Lenze MCM motor series is available in three sizes with power ratings of 0.27 to 3.35 Hp (0.2 to 2.5 kW). In conjunction with Lenze i700, 9400 and 8400 TopLine servo inverters, the economically efficient and powerful MCM motor drive solutions are capable of achieving torque ranges from 5.31 to 233.66 in-lbs. (0.6 to 26.4 Nm). Self-cooling MCM servo motors are optimized with spring-applied brakes, feedback systems and connections, and a comprehensive range of system cables for easy installation.
"Tailored for superior performance in positioning tasks requiring intermediate-level dynamics, MCM motors complement the Lenze portfolio, maximum precision requirements," adds Burns.
The Armature is entirely released by the spring. In spring-applied brakes, wear occurs during starting because the speed increase requires an air buffer to be created between the friction lining and the friction surfaces. Additional wear may occur if the friction disc accelerates as a result of gravitational acceleration in vertical drive arrangements or as a result of centrifugal forces during rotation of the rotor blades of wind turbines,
For IEC Standard Motors without built-on accessories, the position of the cable entry can be selected. For geared motors without built-on accessories, the position of the cable entry must be selected as a function of the terminal box position. The three-phase AC motors can be equipped with a spring-applied brake which is active when the supply voltage has been switched off (closed-circuit principle). In the deenergised state, the brake is applied.
