Three-Phase Induction Motor Slip Calculator

Compute three-phase induction motor slip: synchronous speed n_s = 60·f/p and slip s = (n_s − n)/n_s. Supports slip-from-speed and speed-from-slip modes; automatically flags generator mode (s < 0).

Quick start

Call this tool from your code in three languages.

cURL

curl -X POST 'https://api.elysiatools.com/en/api/tools/motor-slip-calculator' \
  -H 'Content-Type: application/json' \
  -d '{"mode":"slipFromSpeed","frequency":50,"poles":2,"rotorSpeed":1440,"slip":0,"decimalPlaces":4}'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Parameters

Name	Type	Required	Description
mode	select	No	—
frequency	number	Yes	Supply frequency in Hz (50 Hz or 60 Hz are most common).
poles	number	Yes	Number of POLE PAIRS p (not total poles). A 4-pole motor has p=2; a 6-pole motor has p=3.
rotorSpeed	number	No	Required for Slip-from-speed mode. Enter the measured rotor speed in rpm.
slip	number	No

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "motor-slip-calculator",
    "arguments": {
  "mode": "slipFromSpeed",
  "frequency": 50,
  "poles": 2,
  "rotorSpeed": 1440,
  "slip": 0,
  "decimalPlaces": 4
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
