World´s Most Compact
750 W Integrated Servo Motor
PRESS release: May 2022
- JVL A/S, one of the world’s leading producers in the field of integrated servo and stepper motors, has updated it’s very compact 750 W integrated servo motor, MAC800.
Very Compact Motor
The MAC800 has the specifications you would expect of a modern servo motor: continuous torque of 2.38 Nm and peak torque of 6.8 Nm, both at 3000 RPM. However, the length of the motor including the integrated servo controller is only 174 mm.
Its larger sibling, the MAC1200, has a torque of 3.8 Nm RMS and 11.4 Nm peak at 3000 RPM, thus providing 1200 W continuous power with a total length of just 204 mm. Both have the same 84x84 mm flange and shaft diameter of 19 mm. This has only been possible using extremely compact motors and state-of-the-art power electronics.
Vibrations and Temperature
So what about vibrations and temperature? This is probably the most common question asked by customers of integrated motors. As for the other integrated servo motors in the range (50…4500 W) – as well as the integrated stepper motor family – both motor and all electronics have been specifically selected to withstand the rigorous demands required by industrial use.
Power Supply and Energy Savings
Powering this motor is easy since it only requires connection of the main voltage of 1x230 VAC directly at the motor. Control voltage for the encoder and microprocessor circuitry is 24 VDC. In an emergency-stop situation, where an approved relay has cut-off the main power, encoder position and other values are maintained by this control
voltage. Alternatively, of course you can choose the optional absolute multiturn encoder instead, which does not need supply or even a backup-battery.
Furthermore, highly effective switching technology is used to ensure low heat generation resulting in appreciable energy savings.
One of the big advantages of using the integrated MAC motor®s is that you do not need to install a separate servo driver or controller in a control cabinet. This gives you many subsequent advantages: Space savings in your control cabinet, saving of expensive motor and encoder cables, saving time (and money) for cabling, electric noise is minimized due to internal cabling inside a metal housing and furthermore, installation errors between driver and motor are eliminated.
In addition, service is much easier since the motor and controller can be replaced as a single integrated unit. Hence, downtime is minimized and production time is maximized.
As shown in the photo the MAC motor® series use a modular design where you can install the control module needed for the application – no matter if it is a stand-alone axis or a multi-axis system running CANopen, Ethernet, BlueTooth or WLAN.
If you use industrial Ethernet then functionality and handling is similar for all supported protocols: Profinet, EtherNet/IP, SERCOS, EtherCAT, Powerlink and Modbus TCP/UDP.
Using JVL’s universal software MacTalk® you can even change between the different Ethernet protocols just by making a firmware update—it is free-of-charge and you can do it as many times as you like.
All Ethernet modules have built-in Ethernet-switch making cabling easy: you can daisy-chain Ethernet cables from motor-to-motor.
In stand-alone applications you will undoubtedly like our graphical programming environment ePLC™. Writing embedded PLC programs is very easy and can be done even by end-users. You do not have to be an experienced PLC programmer to make ePLC™ programs: the icon-based graphical programming environment does the job for you. Just click on the command icon you want and the program line is created for you.
Programming is similar for all integrated motor families: QuickStep®, ServoStep™ and MAC motor®.
No matter the number of I/O points in the actual motor, each digital input and output and analog input can be used in the program: you can query single or multiple input conditions and branch accordingly to other parts of your program. Motion commands are available with different kinds of relative or absolute movements. Jumps and IF commands, timers and other functions are also available as well as register calculations. All registers and parameters in the motor can be accessed and most can be changed if required.
Connect a suitable color touch operator panel (HMI) and the operators can key-in values and parameters to the motor as well as monitor operations.
