ZHUJIANG FUJI ELEV ATOR CO., LTD.

Foreword

Thank you for using the WYT series gearless permanently magnetic synchronous tractor.

The Maintenance and Operating Instructions describes how to use the WYT series gearless permanently magnetic synchronous tractor in a correct manner. Please read the manual carefully before you carry out any operation, including transportation, installation, maintenance and inspection etc. Only use the tractor after you are familiar with the safety cautions of the product.

General Cautions

●The symbols indicated in the manual are for general purpose, and they may be different from

●During adjustment of the electromagnetic brake, take safety actions to ensure that the car and

the counterpoise have no free movement.

●Do not alter the product.

●Ensure that the tractor’s operation is reliable in the place where dripping or oil leakage is

possible; otherwise do no install the equipment.

●Check the elevator’

●Do not put your hands or articles on the opening part of the tractor.

●Do not use the machine which has problems.

●Do not remove or cover the nameplate.

●Be careful in handling the equipment. Use the hoisting ring, and make sure that the

equipment is not connected to other devices which are to be installed. Before hoisting, check the weight of the tractor and the load of the hoisting equipment. Falling off is not allowed.

●Make sure that the model of the product received is the same as the order model; otherwise

do not install the equipment.

●Do not put flammable articles around the equipment.

●Provide necessary space for heat emission for the equipment.

●The tractor must be driven by the special frequency conversion speed control device. It is

prohibited to connect the tractor to the power supply directly or a driving device which does not meet the requirement.

●Make sure that all fasteners are tightened before installation.

●Pay attention that the rotation direction of the tractor should be consistent with the connected

I.Product structure an operational principle

The gearless permanently magnetic synchronous tractor (hereinafter referred to the tractor) manufactured by our company includes two major series of inner rotor structure (WYT-Y series) and external rotor structure (WYT-S series), and mainly consists of the permanently magnetic synchronous motor, the traction sheave and the brake system. Featuring low speed and big torque the permanently magnetic synchronous motor adopts high-performance permanently magnetic materials and special motor structure. The traction sheave and the brake pulley are in coaxial fixed connection, and are installed on the motor’s shaft extension end directly. The brake system of the tractor consists of the brake body, brake pulley, brake arm and brake shoe. The operational principle of the tractor: Power of the motor outputs torque through the traction sheave by the shaft extension end, and drive operation of the car through friction of the traction sheave and the steal wire. When the elevator stops running, the normally closed brake brakes the brake pulley through the brake shoe to keep the car motionless.
