Product Description:
The 103H7522-72XS42 belongs to the StepSyn Stepping Motors series and is specified with a voltage of 72 V. This voltage rating guarantees that the motor will function within the specified electrical parameters making it suitable for use with systems that are designed under this voltage range. Its defined continuous current capability is 103 A per phase. The device’s pin configuration is a simple 3-pin which eases the layout and interconnection on the board.
The conduction losses during operation are minimized with an On-state Resistance (rds(on)) of 2.5 mΩ. It helps in minimizing the losses contributed during conduction. There is a specified gate charge of 75 nC; this charge is low enough to enable quick switching transitions. The device is able to be modulated with pulsed signals at a rate of 200 kHz switching frequency which makes it possible for the device to operate at high speeds. Its thermal resistance (junction-to-case) is 0.8 °C/W and thermal resistance (junction-to-ambient) is 40 °C/W which will determine the total heat dissipated to the surroundings. The insulation against high voltage spikes is strong as the dielectric withstand voltage is rated at 1000 V.
The specified input capacitance is 350 pF for the stepping motor 103H7522-72XS42. This relatively low capacitance value increases the speed of response in switching circuits. The output capacitance is 500 pF, and it also helps in reducing the rate of unwanted voltage fluctuations during operation. The device has a reverse recovery time of 30 ns. Also, the unit has a maximum power dissipation of 750 W which enables the device to support considerable thermal loads during sustained operation. In addition, the avalanche energy is 200 mJ which enhances the protection during voltage transients.
