Frequently Asked Questions About Armatures
What is an armature and how does it work in a power tool?
An armature is the rotating electromagnetic component inside a power tool motor. It consists of copper wire windings wrapped around a laminated iron core, connected to a commutator. When voltage is applied, the windings generate a magnetic field that interacts with the stator’s field, producing rotational torque. The armature directly drives the tool’s gearbox and output shaft, determining the tool’s speed, torque, and overall performance.
What is the difference between an armature and a stator?
The armature is the rotating part of the motor, while the stator is the stationary housing that creates a fixed magnetic field. In brushed DC motors, the armature contains the windings and commutator, and brushes transfer current to the rotating armature. In brushless motors, the roles are reversed — the stator contains the windings and the rotor uses permanent magnets. Both parts work together: without a properly matched armature, the motor cannot generate useful mechanical power.
How do I know which armature fits my power tool?
To find the correct armature, check your tool’s model number and the OEM part number printed on the original armature’s shaft or commutator. You can also count the commutator segments and measure the shaft diameter and overall length. If you are unsure, send us your tool’s make and model — our team will match it to the correct replacement armature from our catalog of hundreds of compatible models.
Can you manufacture custom armatures for my business?
Absolutely. As an experienced armature supplier with in-house manufacturing, we offer full custom armature development. You can specify shaft dimensions, number of winding turns, wire gauge, commutator segment count, insulation type (Class B, F, or H), and balancing grade. We produce prototypes for validation and scale to full production runs for OEM and aftermarket requirements. Contact us with your specifications.
What brands do your armatures support?
Our armatures work with leading global brands: Bosch (angle grinders, rotary hammers, demolition hammers), DeWalt (drills, saws, impact tools), Makita (grinders, saws, planers), Hitachi (hammers, saws), Skil, KPT, Dongcheng, Black & Decker, and more. We manufacture both standard replacements and custom-compatible armatures for specialized models.
Do you offer wholesale pricing for armatures?
Yes. As a factory-direct armature supplier, we offer competitive wholesale pricing for bulk orders. Our pricing structure scales with volume — larger orders receive better per-unit rates. We accommodate businesses of all sizes with flexible minimum order quantities. Request a bulk quote from our sales team for the best pricing on your volume.
How do you guarantee armature quality?
Quality is built into every step of our manufacturing process. Each armature undergoes: (1) dynamic balancing to minimize vibration and bearing wear, (2) electrical surge and insulation resistance testing, (3) commutator runout and surface finish inspection, (4) dimensional verification of shaft, core stack, and overall length. We follow ISO-compliant quality procedures and provide test reports on request for bulk orders.
How long does shipping take for armature orders?
Standard orders are processed and shipped within 3–7 business days from our China manufacturing facility. International delivery typically takes 7–14 days, depending on destination and customs clearance. Express shipping via DHL, FedEx, or UPS is available for urgent orders (2–5 day delivery). All shipments include real-time tracking and insurance coverage.
