XtraforsPrime servomotor

XtraforsPrime servomotor 1.- Introduction to the Product The XtraforsPrime servomotor is a new product generation that resumes all the knowhow and the new technologies of Mavilor and the group Infranor. The improvement can be found in the design, in the harmony with the drives, the performances and optional solutions

XtraforsPrime servomotor 2. Safety Guidelines 2.1 Appropriate use Servo motors have been designed, developed and manufactured for conventional use in the industry. They were not designed, developed and manufactured for any use involving serious risks or hazards that could lead to death, injury, serious physical damage, or loss of any kind without the implementation of exceptionally stringent safety precautions. Synchronous servomotors are precision motors. They are not intended to be connected directly to a rotary current power supply system. They have to be operated only by a particular electronic...

XtraforsPrime servomotor During transport and storage, devices must be protected from excessive stress ( mechanical load, temperature, humidity, aggressive atmosphere, etc.). Servo drives contain components sensitive to electrostatic charges which can be damaged by inappropriate handling. It is therefore necessary to provide the required safety precautions against electrostatic discharges during installation or removal of servo drives. The installation must take place according to the service manual using suitable equipment and tools. Devices may only be installed without voltage applied and...

XtraforsPrime servomotor CINFRANORMAVILOR2.6 Protection against Touching Electrical Parts Before turning on a servo drive, make sure that the housing is properly connected to ground (PE rail). The ground connection must be made, even when testing the servo drive or when operating it for a short time! Before turning the device on, make sure that all voltage-carrying parts are securely covered. During operation, all covers and switching cabinet doors must remain closed. Control and high power contacts can have voltage applied, even when the motor is not turning. Touching the contacts when the device...

XtraforsPrime servomotor CINFRANORMAVILOR - use safety guards - install light curtains or light barriers - Fences and coverings must be strong enough to resist maximum possible momentum, especially if there is a possibility of loose parts flying off. - Mount the emergency stop switch in the immediate reach of the operator. Verify that the emergency stop works before starting up. Do not operate the machine if the emergency stop is not working. - Isolate the drive power connection by means of an emergency stop circuit or use a starting lockout to prevent unintentional start. - Make sure that the...

XtraforsPrime servomotor CINFRANORMAVILOR - Use lifting devices and tools correctly and safely. - For safe protection wear appropriate protective clothing, e.g. safety glasses, safety shoes and safety gloves. - Never stand under suspended loads. - Clean up liquids from the floor immediately to prevent slipping.

XtraforsPrime servomotor 3.1. - General Description The three-phase synchronous motors from the XtraforsPrime are permanently excited, electronically commutated synchronous motors for applications that require excellent dynamic characteristics and positioning precision as well as compact size and reduced weight. • NdFeB permanent magnets • Sinusoidal commutation with encoder or resolver as feedback unit • Three-phase winding with star connection • Compact sizes result in low weight • High overload capability/peak torque • 0 Cogging torque due to it’s special construction without slots in the...

XtraforsPrime servomotor EMF constant Voltage that the motor gives as a generator between two terminals at certain speed, the voltage is measured in rms value and the speed in rad/s The value is given in Vs/rad Torque constant The ratio between the current (in rms value) is supplied to the motor and the torque in the output shaft, measured in Nm The value is given in Nm/A Reluctance torque (Cogging) The maximum torque needed to move the shaft without power. It characterizes the stepping effect of the rotor which should be as low as possible. The value is given in Nm Winding resistance The resistance...

XtraforsPrime servomotor Mechanical time constant It characterizes the speed increase for an input voltage step. The value shows the time to achieve the 63% of the maximum speed for the input voltage. The values is given in s Electrical time constant It characterizes the current increase in the motor winding for a voltage step The value is given in ms when L is in mH and R in Thermal resistance It is the temperature difference across a structure when a unit of heat energy flows through it in unit time The value is given in ºC/W

XtraforsPrime servomotor CINFRANORMAVILORMass It is the weight of the motor without accessories. The value is given in kg It expresses the shaft radial load applied in the middle of the output shaft, which will give a basic rating life of the bearings of 20000 hours It expresses the shaft axial load which will give a basic rating life of the bearings of 20000 hours It refers to the maximum operation temperature allowed CHARACTERISTICS SYMBOL UNITS
