New servo motors top the charts
The new MCA and MQA series of asynchronous servo motors from Lenze deliver more power than comparable motors as a result of a revised cooling concept. A common mechanical design with three different forced ventilation options can deliver up to 200 percent more power at a given inertia. Lenze says that, combined with other state-of-the-art features such as insulated bearings and electronic nameplates, this makes the MCA and MQA motors an ideal choice for economy and long life.
MCA and MQA motors are available with rated torques up to 125Nm and a massive reserve for peak torques up to 500Nm. The high power density is a result of the forced ventilation design. At the lowest level are IP54 motors with conventional external forced cooling. Achieving an increase of about 10 percent at the expense of reduced enclosure to IP23 is done with a radial blower that forces air through internal channels in the motor. A further increase of about 25 percent is available through a larger blower mounted radially.
All three versions deliver high powers and torques for their size, but the radially blown models are exceptional in combining high power and high torque with low inertia. Compared to other motors of a similar inertia, these motors are claimed to deliver two to three times more power. There is space saving too - these motors give 20 to 30 percent more power for a given volume. The result is better dynamics on high speed machinery from the increased ability to inertia match together with savings in cost and space.
