China Electric Car Motor Kit Factory – PX series miniature current geared motor – INDEX Detail:

Overview

J-SZ(ZYT)-PX series miniature DC geared motors are respectively composed of SZ(ZYT) series DC motors and PX type ordinary precision planetary reducers, and equipped with power supply, which can realize stepless speed regulation. Wide adjustment range, small size, light weight, high efficiency, compact structure, large output torque, widely used in drives that require low speed, high torque, and stepless speed regulation. Infinitely variable speed.
PX series planetary gear reducer can be directly connected to AC motors, stepper motors and other motors.
PX series can also be directly connected to worm gear reducer and cycloidal pinwheel reducer to form reducers with different speed ratios or large speed ratios.

Non-standard reducers such as special speed ratio, speed, installation size, etc. can be designed

Selection example
The user can correctly select the power and model of the reducer according to the actual working system and the nature of the load by referring to the following contents.
1.  According to the load torque and the output speed of the reducer, the required power can be calculated by the following formula: P=T n/kh
In the formula: P- output power W T - load torque Nm, select     n- output speed r/min according to the technical data sheet
K- load constant 9560    η - transmission efficiency, selected from the following table

Transmission Ratio

Transmission ratio(i)	4(6)	16(36)	64(216)	256(1296)
η	0.76	0.72	0.68	0.65

2. The motor governor can be selected to realize the stepless speed change of the reducer from O to the rated speed.
3. According to the actual working system and load nature, the service coefficient can be selected with reference to the service coefficient table. After calculation, the required power of the reducer can be determined, and according to the required output speed, the reducer model can be selected by referring to the technical data table.

Working Index Sheet

Daily Work Time	Load Level
	Average steady	Medium vibrant	Heavily impact
12	1	1.25	1.75
24	1.25	1.50	2

For example: if the load is even and stable, the required motor rated power is 40W, the rated voltage is 110V, the output speed ratio is 4, and the working time per day is 12h, then 40W is selected . If the nature of the load is moderate vibration:
Then: a. Refer to the service coefficient table to select the service series as 1.25 . Required power W=40W*1.25=50W
b. Check the technical data sheet for optional J70SZ54P*4
