Product Description:
The PMM-BA-4803-1 pulse-motor driver is manufactured by Sanyo Denki as part of the PM Drivers series. It supplies timed current pulses to two-phase stepper motors, converting controller commands into rotational or linear displacement for indexing tables, feeders, or small gantries in automated equipment. By combining power conversion, signal conditioning, and fault detection in a single enclosure, the unit simplifies integration into motion axes that require moderate torque and precise incremental positioning.
The driver accepts a single-phase AC input of 100/115 V at 50/60 Hz, allowing direct connection to common service lines. Its output stage delivers up to 2 A per phase to the motor windings, while a separate 3 A supply supports the control electronics and auxiliary devices. The driver tolerates a +10% to -15% voltage variation without a loss of performance. Internally generated pulses can be processed at rates up to 100 kpulses/s for high-speed microstepping. Electrical isolation is reinforced by a minimum insulation resistance of 10 MΩ between the power circuits and grounded chassis. For cabinet mounting, two M4 × 0.7 holes placed on a 147 ± 0.5 mm pitch allow rigid attachment to a suitable panel surface.
Supervisory protection is provided through an alarm relay rated at 24 VDC and 0.5 A maximum, permitting a direct interface with PLC input cards. Command lines have an input impedance of 330 Ω, ensuring reliable triggering from open-collector or line-driver sources. The power section has a dielectric withstand capacity of AC 1,000 V for 1 minute between the applicable circuits. The aluminum housing weighs 2 kg and measures 200 mm long, 140 mm high, and 47 mm deep, allowing the driver to fit behind shallow panel doors without interfering with adjacent components. Passive ventilation slots run along the sides of the enclosure to support heat dissipation during operation. The mounting pattern is incorporated into the baseplate, providing secure attachment without a separate mounting bracket.
