3 The PMT gearmotor is a parallel shaft gearbox combined with a safe and reliable brake motor studied for hoisting application. The design is based on the AMD (advanced modular design) system which allows multiple product configuration thanks to the completely modular design of this system. See dedicated section of this catalogue to check the different possible configuration possibilities. The modular system also allows the mounting of different types of motors depending on the real need of the application; DC or AC3 phase brake, standard or increased protection degree, for marine application, Explosion proof version and many others. The PMT drive system is studied in order to obtain the highest possible performance in terms of silent running, reliability, long life, easy maintenance. GEARBOX - 3 stage gearbox - Fine machining of the gears for low losses and silent runnig - Cast Iron (aluminium for PMT65) construction light weight to combine high mechanical resistance, any environment application and easy handling. - Modular design prepared for mounting with interface flange, base mounting or customized requirements - Integrated bearing support of drum and double bearing support with flange interface mounting type - Output shaft available in DIN 5480 or special design requirement - Increased axle distance for drum easy mounting BRAKE MOTORS - Heavy duty design - High starting torque - High brake torque - Limited maintenance - Three phase or DC brake - Protection degrees from IP54 to IP66 for motor and brake - Version for marine application - Explosion proof version - Versions with forced ventilation, encoders, and many optionals available (see COEL general catalogue for details) 1

4 The PMT drive system is designed so to allow different mounting possible solutions. The main possibilities are: with interface flange and shaft direct on drum, ready for mounting direct on drum (in this case the end user must define his own coupling solution) and base mounting with juction (see dimensional drawings of this catalogue for further details). FLANGE AND SHAFT DIRECT ON DRUM Flange and shaft interface Flange and shaft interface Double bearing support for drum Possibility of second output shaft for auxiliary device thanks to the double output face of the gearbox PMT look PMT mounting example READY FOR MOUNTING DIRECT ON DRUM Hollow shaft and mounting pad ready for easy adaptation of any interface PMT look PMT mounting example Possibility of second output shaft for auxiliary device thanks to the double output face of the gearbox BASE MOUNTING WITH JUNCTION Possibility of second output shaft for auxiliary device thanks to the double output face of the gearbox 2 PMT look PMT mounting example

5 The PMT gearmotor is completely modular. For this reason, moreover the different mounting possibilities, you can also choose for different types of brake motors depending on the application requirements. All the motors and the brakes mounted are manufactured by COEL (see and designed to ensure the highest possible reliability in all the working conditions. The following description shows the general characteristics of the different type of motors in order to semplify your choice. F F K Designed for very heavy duty has the following features: - Oversized brake for long life and limited maintenance - Brake with magnet 3 phase AC or DC+rectifier - Braking surface ventilated and separated from the motor in order to improve the brake performance - Real IP55 protection of the brake and motor - Hand release screw of the brake as series - Motor body in die pressed aluminium - Available with many options (please see COEL general catalogue for details) Designed for heavy duty and similar structure to other manufacturers brake motors - Adequate diemensioning of the brake - Brake with DC magnet with rectifier - IP54 degree protection (IP55 on request for motor part) - Lateral hand release available on request - Motor body in die pressed aluminium - Available with many options (please see COEL general catalogue for details) S W Designed for heavy duty suitable for marine duty or any application requiring real certified IP66 protection - Adequate diemensioning of the brake - Brake with magnet 3 phase AC or DC+rectifier - IP66 certified protection - Motor body in die pressed aluminium or in cast iron on request - Supplied as series with forced ventilation - Available with many options (please see COEL general catalogue for details) Explosion proof version with following features: - ATEX certified - Modular design with separate motor and brake unit - AC 3 phase or DC brakes - Cast iron construction - Up to Category: 2 G / 2D /2GD Type Ex d / Ex td A21Enclosure group: II B / II C Temperature class: T3 / T4 / T5 Protection degree: IP66 Ambient temperature -20 or -50 C / +55 C. 3
