Product name: YTD335 [Technical data sheet]
[The outlook and installs the size ]
Characteristic and use:
The motor has two separated sets of windings. The 4-pole winding or 6-pole winding is used for starting and running, the 24-pole winding used leveling and braking and can also be used for low-speed starting and running for a short period of time when the elevator is under installation or maintenance. The degree of protection of enclosure of the motor is drip-proof, conforming to specification of IP01. The cooling method of the motor is forced ventilation by an independent blower, conforming to specification of IC06. Type of construction and mounting arrangement is horizontal flange mounted. The motor is suitable for the voltage and speed adjustable elevator and two-speed elevator, can be mounted on all kinds of mechanical gear-down traction machine, which can meet the operating condition of frequent starting and braking of 180 cycles per hour.
Electrical machinery performance:  

The motors are applicable to voltage-regulating adjustable speed elevators, meeting the operating condition of frequent starting and braking of 180 cycles per hour.
The starting torque of 4-p or 6-p of the motors is 2.2 times of the rated torque, and that of 24-p is 1.4 times of the rated torque.
The starting current of 4-p or 6-p of the motors is 4.5 times of the rated current.
On the rated torque, the slip of 4-p or 6-p of the motors is 8%, and that of 24-p is not over 20%.
The insulation class of the motors is class F.
There are thermistors embedded in windings of the motors, and their leads are connected into the terminal box. The appropriate thermal protective relay may be selected by customer to realize the overheat protection of the motors.
Under the condition that the ventilating blower is operating, the period for short-time running of 24-p should be limited in 3 min from the cold state of the motors.
On the condition that the shaft-extension is fitted with a half-key, the effective value of vibration severity of the motors is not over 1.12 mm/s measured at no-load operation of 4-p or 6-p.
The noise of A-weighted sound pressure level (Lp) of the motors is not over 70 dB measured at no-load operation of 4-p or 6-p.

Model explanation:  

Structure synopsis:  
The protection degree of enclosure for the motors is the drip-proof type, conforming to the stipulation of IP 01.
The method of cooling for the motors is the forced ventilation with an independent blower, confirming to the stipulation of IC 06.
The construction and mounting type of the motors is the horizontal flange mounted, with double shaft-extensions (IM3002).
The motors are equipped with rolling bearings.
The motors have two sets of separate windings. The 4-p or 6-p winding is used for starting and running; the 24-p winding is used for leveling and braking, and be also used for low-speed starting and running at installation or maintenance of the elevators.
Content:  

Please write clearly the motor type, power,rated voltage, rated frequency,number of poles,mounting and construction type when ordering.
For the frequency converting elecator motor,it should be specified what kind of encoder would be fitted and whether to be with thermistors and so on.
If any particular requirement is needed in the motor type,power, rated voltage, rated frequency, number of poles, etc., please indicate it for consultation before an order is placed.
