Terms of Service for Variable Frequency Drive Sourcing

These terms govern use of the Variable Frequency Drive Sourcing website. Variable Frequency Drive Sourcing is an independent sourcing partner that coordinates factory quotations for variable frequency drive equipment. Submitting an inquiry does not create a purchase contract, appoint an exclusive agent, or make this site a brand-appointed reseller of any OEM.

Quotations and scope

Factory replies remain the supplier’s statements. We compare written scopes. We do not warrant machine performance, certification coverage, inventory or delivery dates. Screening aids, including any internal kilowatt estimate the buyer used, are not acceptance results issued by this site.

Buyer information

You are responsible for the accuracy of specifications, quantity, destination and optional budget notes you submit. Drawings described in the form may be shared with candidate factories for quotation only.

Site content

Pages are procurement guidance. They are not engineering stamps, safety certificates or legal advice. Linked manufacturer documents are third-party references.

Limitation

To the extent permitted by applicable law, Variable Frequency Drive Sourcing is not liable for indirect losses arising from use of this website or from a later purchase contract between you and a factory.

Replacement versus new installation

Existing process

If a variable frequency drive is replacing a starter or an older inverter, photograph cabinet depth, motor-cable length and the analog or digital control that currently holds pressure or airflow. A new frame that ignores those connections creates field changes that never appeared in the first quote.

Replacement is a different interface list than a new pump or fan cell; it is not automatically a smaller project.

Compatibility checks

  • Envelope and footprint after the old starter is removed, including heat-sink clearance and IP rating of the proposed enclosure.
  • Connection to existing motors, including who supplies output filters, shielded cable and bypass contactors.
  • Operator restart method: local keypad, remote dry contact, or PLC interface after a sensor-loss alarm.
