Integrated Stepper Motors Feature CANopen Connectivity

Applied Motion Products of Watsonville, CA have just released a new line of High Torque Integrated Stepper Motors with built-in CANopen communications.  The STM24 Series is a Nema 24 frame hybrid step motor series with holding torque rated to 340 oz-in .

CANopen is a standardized communication protocol for use in distributed automation control systems.  It is a popular fieldbus option for applications that require the transmission of time-critical data to and from the devices on the network.

The STM24 CANopen Integrated Motors adhere to CAN in Automation (CiA) specifications DS301 and DSP402.  Profile Position, Profile Velocity, and Homing modes are fully supported at data rates up to 1 Mbps.  Applied Motion also provides specific CANopen objects for executing stored Q programs* and accessing internal data registers in the products.

Each STM integrates a NEMA step motor, microstepping drive and controller into a single device, offering savings on space, wiring and cost over conventional motor and drive solutions.

The "S" version models accept step and direction, analog input, joystick control, and streaming host commands using the SCL language. "Q" version models add stand-alone programmable operation using the Q programming language. This versatile language includes high-level features such as complex motion, multi-tasking, conditional programming, math functions, register access, and more. Both S and Q models offer RS-232 or RS-485 communication.

An optional 4000 count encoder, integrated into the motor housing, provides stall detection and stall prevention.  Applied Motion's proprietary stall prevention algorithm monitors rotor lag and automatically reduces speed and acceleration to avoid motor stalls, allowing 100% torque utilization.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
