440 Vac Motor Startor Single Phase Slip Ring Assembly

Part No. 440 Vac Motor Startor Single Phase Slip Ring Assem

440 VAC single-phase slip ring assembly for motor starter duty — carries rotor current from a wound-rotor motor to the external starting resistance via brushes for low-current, high-torque starting. Ring count, bore and circuit details to be confirmed per SKU.

Application	Slip-ring assembly for the motor starter circuit — in wound-rotor (slip-ring) motors, the rotor winding connects to the external starting resistance through the slip rings and brushes, giving low starting current and high starting torque; also used wh
Voltage	440 V AC (user-provided) — standard rating class for wound-rotor motors (380

Description

Overview

440 V AC slip ring assembly for motor starter circuits — part of the wound-rotor (slip-ring) motor starting system: the rotor winding connects to the external starting resistance through the slip rings and stationary brushes, enabling controlled starting current and high starting torque.Alibaba.com

How It Works in the Starter Circuit

Rotor windings → slip rings → brushes → external starting resistance
Resistance limits starting current; resistance is cut out as the motor accelerates
Rings are shorted/isolated at running speed per the starter scheme

Typical Duty

Wound-rotor (slip-ring) motors with resistance starters (440 V class)
Slip-ring motor starter systems (rotor resistance / LRS-type)
Special single-phase wound-rotor machine starting circuits

Before Ordering — Confirm
