PMSM Gearless Traction Motor | HAYASHIMU Sino-Japan Technology

HAYASHIMU PMSM Gearless Traction Motor represents a perfect synergy of Chinese manufacturing excellence and Japanese precision engineering. Built around Sino‑Japan Technology, this permanent magnet synchronous motor (PMSM) redefines vertical transportation by eliminating the need for a gearbox. The result is a drive system that operates with near‑silent efficiency, drastically lowering energy consumption while providing exceptional ride comfort for the elevator car. Whether deployed in residential buildings or demanding commercial building environments, this motor sets a new benchmark for reliability and performance.

Versatile Performance for Modern Architecture

This PMSM gearless solution is engineered to handle a wide spectrum of applications. It supports a rated payload from 450kg to 2000kg, making it suitable for everything from small residential lifts to high‑capacity systems in high rise buildings. The rated speed ranges from 0.63m/s up to 2.0m/s, offering the flexibility to transport people smoothly in low‑rise apartments or at high speed in skyscrapers. As one of the most critical elevator components, durability is paramount. The motor carries a Protection Class of IP41, safeguarding internal electronics and mechanical parts against dust and dripping water—a vital feature for machine‑room installations that demand long‑term reliability.

Technical Specifications That Matter

The technical architecture of the HAYASHIMU PMSM motor is designed for precision and longevity. The complete unit weighs 360 kg, providing a stable, vibration‑damped foundation that minimizes noise transmission into the building. Its braking system operates at a Brake Voltage of DC110V with a Brake Current of 2×1.35A, ensuring instant, fail‑safe holding of the elevator car under all load conditions. The Number Of Motor Poles is 32, a configuration that delivers high torque at low speeds without the energy losses associated with geared systems. Rated with an Operating Mode of S5 40%, it is built for the intermittent start‑stop cycles typical of vertical transportation—frequent starting, stopping, and electric braking that mirror real‑world elevator usage. By integrating the HAYASHIMU PMSM Gearless Traction Motor, developers and building owners gain a future‑ready solution that combines Sino‑Japan technological prowess with practical, low‑cost operation.

Q/A: PMSM Gearless Traction Motor | HAYASHIMU Sino‑Japan Technology

Q: What makes the HAYASHIMU PMSM Gearless Traction Motor different from traditional geared machines?
A: The HAYASHIMU motor uses permanent magnet synchronous technology with a gearless design, eliminating the energy losses and noise associated with gearboxes. This results in significantly lower energy consumption, quieter operation, and reduced maintenance. It is particularly advantageous for residential buildings and high rise buildings where noise control and long‑term efficiency are essential for modern vertical transportation.

Q: What are the capacity and speed ranges for this motor?
A: The motor supports a rated payload from 450kg to 2000kg, covering a wide weight capacity spectrum from small residential lifts to heavy‑duty commercial systems. The rated speed is adjustable from 0.63m/s to 2.0m/s, allowing it to efficiently transport people in both low‑rise apartments and high‑speed commercial building elevators.

Q: How does the IP41 Protection Class benefit installation?
A: The IP41 rating ensures the motor is protected against solid objects larger than 1mm and vertically dripping water. This makes it suitable for machine‑room environments where dust and moisture may be present, extending the lifespan of these critical elevator components and ensuring reliable operation of the elevator car.

Q: What is the significance of the S5 40% operating mode?
A: Operating Mode: S5 40% indicates the motor is designed for intermittent periodic duty with electric braking—the exact duty cycle of elevators that frequently start, stop, and brake. This rating ensures the HAYASHIMU PMSM motor can handle the rigorous demands of vertical transportation without overheating, providing consistent performance in high rise buildings and other high‑traffic applications.
