ERPD Motor for Green House
The EP PolyDrive (RPD) is a compact and lightweight motor motor with an integrated limit switch system for driving manually-controlled or climate-controlled ventilation and screen systems in poly greenhouses. The quick and easy-to-installEP PolyDrive is rainproof and windproof. The PolyDrive has a high protection class (IP55) and can be used in an ambient temperature of 0-60 °C. The low-noise PolyDrive motor motor has a gearwheel transmission and a worm wheel transmission, which are integrated in an aluminium precision housing. The self-braking worm wheel transmission ensures that the drive shaft is locked when the reduction motor is not running. The fully sealed reduction motor has an expansion chamber with a diaphragm to keep the gear oil at a low pressure under all circumstances, even at high temperatures. Thanks to the use of an expansion chamber, the PolyDrive can be installed in any position. There are no restrictions, because there is no need for a bleed plug. The sealed reduction motor keeps the gear oil of the PolyDrive in optimal condition for its entire operating lifetime. The PolyDrive is suitable for discontinuous use, operating class s3-30%, with a maximum activation time of 25 minutes. All PolyDrive motor motors are available with 3-phase, 400 V standard motors (EN 50347). The 150 Nm and 3 rpm PolyDrive motor motors are also available with 3-wire, 1-phase 230 V or 115 V electric motors.The PolyDrive motors have a hexagon in the motor shaft so that the motor motor can be driven manually in the event of a power cut. The PolyDrive has a rotating limit switch system with operating switches and circuit breakers (NC contacts) for turning off at the end positions. The limit switch system is installed in an integrated chamber and is enclosed by an impact-resistant plastic cover. The limit switch system is accessible and easy to adjust. The limit switch system’s maximum switching range is 40 or 64 revolutions of the drive shaft.
The cabling is connected in spring-clip connections. The PolyDrive has an IP68 M16 x 1.5 cable gland (5-9 mm cable) for the cable feed-through. The PolyDrive can be optimally controlled by theEP MotorControl RMC400. This control system continuously controls, inspects and protects the PolyDrive. To protect the PolyDrive against being overloaded, its electric motors are equipped as standard with a PTC thermistor. The PolyDrive comes with 16 teeth 5/8”x3/8” sprockets, keys and fasteners. The accompanying chain couplings and assembly plates are available as accessories.
