400VA 70V TOROIDAL TRANSFORMER for CLOSED LOOP STEPPER HYBRID SERVO MOTOR CNC

Description

If you’re sourcing a transformer for your closed loop stepper system based on the popular 24-80VAC drives, this is the right transformer:
•
OPTIMIZED VOLTAGE.
Voltage is the pressure that forces current into the stepper’s coils.
The faster the rotor turns, the less time for the coils to saturate, hence
torque falls as speed increases. Few toroids being offered for stepper
motor application put out more than 60V. That’s not bad, but the
sweet spot for motor performance is 70V. This leaves a 10V margin
to ensure long life for the drive.
•
MOST EFFICIENT DESIGN.
Toroidal transformers are well-suited for noise sensitive
environments such as CNC control cabinets and powering stepper
and servo drives. Voltage drop under high current draw is very low,
which is important when your depending on relies on relays,
solenoids, etc to operate reliably.
•
FIRST RATE MATERIALS & BUILD QUALITY.
Construction materials meet all major industry standards including
100% copper wire, Nippon Steel Co. core material, ROHS compliant,
UL standards and CE certifications. Check the jpeg attachments for
the bill of materials quality standards.
