Structure synopsis
1.Protection, mounting and type of construction: a. Type of protection of the whole series: IP21S b. Mounting modes comply with the State Standard GB/T997 stipulated as follows:
2.Methods of Cooling: Modes of cooling for all the motors are separate cooling, force ventilated. Cooling by frame radially mounted, separately powered ventilating fan, and attached with an air filter. Modes of cooling for motors may be made into three types, namely IC06, IC17 and IC37. a.For Z4-100-Z4-160, the blower is mounted on the non-drive side. b.For Z4-180-Z4-450, the blower is mounted on the drive side.
   All the ventilating fan motors are of three phase, two pole, 380V. Motors with the following five methods of cooling can also be ordered, but prior consultations are needed. a. Frame size 100 up to 250 may be made into the totally enclosed, frame cooled motor (IC410). b. Frame size 160 up to 250 may be made into the separately ventilated motor with blower mounted on its non-drive side (IC05). c. Frame size 100 up to 200 may be made into the self cooled open motor with its own fan mounted on the shaft (IC01). d. Frame size 160 up to 355 may be made into totally enclosed motor with internal cooling air circulation by independent air-air heat exchanger mounted on it (IC666). e. Frame size 160 up to 450 may be made into totally enclosed motor with independent air-water heat exchanger mounted on it (IC86W). 3. Standard terminal box mounting is the right hand side seen form the drive end of the motor. As an alternative, mounting at the top or on the lefthand side is possible on request. 4. Motors if needed, can be fitted with tachogenerator or other accessories at the non-drive end. 5. Motors, when directly coupled, must use elastic or flexible couplings. The drive and driven units must be aligned with the utmost care. Radial forces acting on the shaft-extensions (belt or pinion drive) must not exceed the values given in the diagrams in the following pages (see Appendix2). Motors are of compact structure, elegant appearance, spacious terminal box, easy wiring, servicing and maintenance.

Yuhai Company is engaged to research and development of piezoelectric products and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.
The ultrasonic transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive ultrasonic sensor is actually a microphone that can convert ultrasonic signal into electrical signal.
According to the working principle and materials used, the ultrasonic transducer has piezoelectric transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
