Applied Motion Products now offers NEMA 34 frame StepSERVO Integrated Motors. The addition of these larger frame sizes in the successful StepSERVO product offering represents a widening of the product range, which already included smaller frame sizes NEMA 11, 17, 23 and 24.
With the larger NEMA 34 frame size, StepSERVO Integrated Motors can now install in more demanding applications where greater torque is required.
High torque from the integrated motors
TSM34 and TXM34 StepSERVO integrated motors come in four lengths, offering machine designers a broad range of torque values to choose from. The longest motors (-6) offer holding torque values of 1,161 oz-in. (8.2 N-m) and peak torque values over 1,300 oz-in. (9.2 N-m). TXM34 integrated motors are IP65 rated with M12 connectors for all connections and a shaft seal at the front shaft. TSM34 integrated motors are IP40 rated with screw terminal and pluggable connectors for power, communication, and I/O connections.
Dual-port Ethernet for motor communications
A highly anticipated feature of the NEMA 34 StepSERVO Integrated Motors is dual-port Ethernet, which simply means two Ethernet ports per motor instead of one. The motors can now be connected (daisy-chained) in a line network topology in addition to the traditional star network topology. This small but important improvement allows for cost savings and design simplification via the reduction of cable lengths, the omission of bulky cable runs, and the downsizing of network switches.
Multiple control and communication options
TSM34 and TXM34 integrated motors support a wide variety of control options, including step & direction, velocity and streaming command modes. They also support stored program execution using Applied Motion’s Q programming language.
Communication options include dual-port Ethernet, RS-232, RS-485, and CAN bus. Communication protocols include Serial Command Language (SCL) over RS-232, RS-485, Ethernet UDP and TCP/IP; EtherNet/IP; Modbus RTU and TCP; and CANopen. All TSM34 and TXM34 StepSERVO integrated motors include two power supply connections, main and auxiliary … so that motor power can be removed while maintaining power to the controller and communications.
This feature eliminates the need to re-home the system after an emergency stop (e-stop) event, and for many applications this can provide the same end result as using a motor with an absolute encoder.
