In the past ten years, we has developed our main product TYJ50-8 Series motor into nearly 400 specifics with a yearly output of 60 million. The stepper motors of model 28BYJ48, 35BYJ46 and 24BYJ48 are now under mass production as well as more than 400 types of huge torque and bidirectional controllable motor. This series of motor is simple and compact in structure and reliable in use. It is equipped with decelerating gears and eccentric axes structure, the maximum rotation speed is 100r/min and the minimum is 0.1r/min, clockwise or counter clockwise rotation is available. With low noise, limited temperature rise (Noise is required to be under 40db and temperature rise to be within 60k in the company) and the ability of starting up consequently and running continuously, the machinery structure meets the safety demands of “GB12350-90 Low-Power Electrical Machine Safety Standards” and the relevant regulations of UL2111.The main insulating parts of the production electrical machine are all safety approved and are accord with the standards of fire prevention, heat resistance and insulation etc.
