IEEE 87-1961

87-1961 is an inactive technical standard for voltage motor controllers used in rubber and plastics industries. It addresses the control of motor-driven equipment where dependable voltage regulation and coordinated operation can affect process stability, machine response, and equipment protection. For manufacturers, integrators, and buyers working with industrial electrical systems, this document provides a focused reference for design and evaluation in applications where motor control is tied closely to production consistency and safe operation.

87-1961 overview

This standard is concerned with voltage motor controllers in an industrial setting, particularly equipment associated with rubber and plastics processing. As a product specification, 87-1961 helps define the technical expectations for controller behavior, electrical performance, and suitable application boundaries. Its relevance is strongest where motor control must support repetitive machine cycles, variable loading, and dependable start-stop or speed-related functions. The document is useful when comparing equipment options or checking whether a controller design aligns with established requirements.

Typical use cases

Common use cases for 87-1961 may include motor control in processing lines, auxiliary drive systems, and machinery used in forming, mixing, conveying, or handling rubber and plastics materials. It is relevant where voltage-controlled operation supports predictable equipment response and where plant engineers need a consistent basis for specifying controllers. The standard may also help in procurement decisions for replacement units, production-line upgrades, and electrical design reviews involving industrial motors and associated control circuits.

Why this standard matters

Using 87-1961 as a reference can support clearer design control, more consistent equipment selection, and better alignment between engineering intent and installed hardware. In industrial environments, that can reduce ambiguity during testing, maintenance, and procurement, especially when controller performance affects process continuity. For inactive standards, the document still has value as a historical technical reference when reviewing legacy systems, evaluating older installations, or comparing earlier requirements with later control practices.
