Gripper Sizing — Electro-Permanent Magnet Gripper
Holding-force and sizing math for a electro-permanent magnet gripper including acceleration and safety factor.
Magnet catalogs quote pull on ground, clean, thick steel — a fairy tale on real parts. Scale, paint and thin sections gut the rating, hence safety factor 3 and the gap derating here. Electro-permanent types hold power-off: a power cut does not drop the part.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Gripper Sizing — Electro-Permanent Magnet Gripper
Gripper Sizing — Electro-Permanent Magnet Gripper computes the governing relationship F_catalog = m(g+a)·SF / derate(gap) live as you type. Magnet catalogs quote pull on ground, clean, thick steel — a fairy tale on real parts. Scale, paint and thin sections gut the rating, hence safety factor 3 and the gap derating here. Electro-permanent types hold power-off: a power cut does not drop the part. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Gripper Sizing — Electro-Permanent Magnet Gripper
- 1Enter your values — Part mass (steel), Peak acceleration, Air gap (rust/paint/scale), Safety factor (sensible defaults are pre-filled).
- 2Read the live results: Catalog force needed, As catalog rating.
- 3Check the "with your numbers" line to see F_catalog = m(g+a)·SF / derate(gap) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Gripper Sizing — Electro-Permanent Magnet Gripper?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula F_catalog = m(g+a)·SF / derate(gap) with authoritative sources cited on the page (Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH))
- ✓Magnet catalogs quote pull on ground, clean, thick steel — a fairy tale on real parts.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the gripper sizing — electro-permanent magnet gripper use?+
It evaluates F_catalog = m(g+a)·SF / derate(gap), exactly as published. Sources: Schmalz — Vacuum handling calculation basics; Monkman et al., Robot Grippers (Wiley-VCH). The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Magnet catalogs quote pull on ground, clean, thick steel — a fairy tale on real parts. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
When is this calculator the right tool for the job?+
Holding-force and sizing math for a electro-permanent magnet gripper including acceleration and safety factor. A free industrial robot kinematics & cell design tool. Scale, paint and thin sections gut the rating, hence safety factor 3 and the gap derating here. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
