LS PR Single Phase Induction Motor (Voltage Relay)
Leroy Somer Motors
The LS PR series from Leroy-Somer provides a robust and efficient solution for applications requiring strong starting torque and reliable operation under variable loads. These single-phase motors are fitted with a voltage relay-controlled starting capacitor, which enhances starting performance compared to permanent capacitor-only models. This makes the LS PR ideal for machinery with high-inertia loads or frequent starts and stops.
Features
The LS PR motor features a voltage relay that controls the inclusion of a starting capacitor during start-up, providing increased starting torque to handle heavier load requirements. Once up to speed, the relay disconnects the capacitor, allowing the motor to run efficiently. Standard IP55 ingress protection makes the motor suitable for dusty or damp environments, and optional thermal protection and reinforced insulation allow for enhanced safety and longevity in demanding setups. Flexible mounting configurations (B3, B14, B34) simplify installation across a variety of equipment.
