Cooler servos

As automation drives are continuously becoming smaller and more powerful at the same time, the need for thermal management increases. A new motor series offers individual application-specific cooling methods.

The new servo motors PMCtendo SZ from Pilz are now available in different cooling types. Due to their small overall length and low weight, all the servo motors have a high power density. PMCtendo SZ are characterised by comparatively quiet operation and suitable process quality thanks to low cogging torques. As a result, the servo motors are meant for use in applications with on-board axes and in cramped conditions.

With their special heat dissipation method and the the high resolution absolute value encoder systems, high performance and absolute positioning is ensured. The high efficiency factor makes it possible to exceed the requirements of the international efficiency class IE 4.

All motors are available with different cooling types - as water coolers, with external fans or with natural convection. The models with external fans offer higher performance, as do the water-cooled motors, which achieve around 35 per cent higher performance than the basic convection model. The latter can also be used with high ambient temperatures.

I have a CNC motor controller 3 axis Toshiba TB6560AHQ and 3 BS57HB56-03 Stepper Motors but when I power up the sysemts after while my motors “gets hot” without using them (in non operational mode) is that any normal? Do you know if Mach3 v R1.83 can work with USB to Parallel port converting pluck? Because I have a laptop with no Parallel port so I bought a USB to Parallel port converting plucks “any suggestions welcome” Thanks

I’ve been recommended by a few friends to opt for a frameless motor. Most of them have said that these motors help improve dynamic performances, and allow addressing applications with demanding constraints on volumes and weights. Should these frameless motors really be preferred over other motors we traditionally use?
