DC MOTOR is a motor converts supplied electrical energy into mechanical energy. Various types of motors are in common use. Brushless DC motor (BLDC) ,also known as an electronically commutated motor (ECM or EC motor) features high efficiency and excellent controllability. The BLDC motor has power-saving advantages relative to other motor types. As professional ec motor manufactrurers our brushless motor main uses in air conditioner or fan coil unit or centrifugal fan.

This dc motor is designed to use in evaperator cooler, air cooler, as evaperator fan motor.
Fan Motor Structure
Fan motor structure is very simple in construction. Our dc fan motors consist of a stator and contain a rotating rotor inside, which is surrounded by pole-pieces and also control panel. The fan motor types and sizes are very different and differentiate heavily among themselves.
All our fan motor complies with the appropriate International Standards as far as:
output
performance
dimensions
Minimum energy performance standard are concerned.
Temperature Range And Altitude
In general our ac fan motor can operate in ambients from -30°C to +50°C at altitudes up to 1000 metres above sea level. Fan motors to operate outside this range can be supplied if required.
Enclosure Standard
The minimum is IP44 in accordance with the appropriate standards. IP54 even IP55 enclosure can be supplied for fully weatherproof applications.
Finish of Fan Motor
Standard finish is enamel paint top coat on suitable primer to give good appearance and protection for general usage. Also aluminum housing with lower temperature rise is available.
Bearings of Fan Motor
Unless otherwise nominated, all our fan motors are fitted with ball bearings. The bearing housing of fan motor up to frame size D140 as a minimum, are fully enclosed, sealed-for-life and therefore do not require maintenance. Bearings are pre-packed with grease and, under normal circumstances, last for several years.
Electrical Supply of Fan Motor
Motors are generally wound for 110-115V/60Hz or 208-240V/50Hz one phase fan motor, however, we can provide fan motor wound for all voltage and frequency variations.
Insulation of Fan Motor
Insulation to Class B with Class B temperature rise is used throughout, allowing for operation in ambients up to +40°C. Fan motor for higher temperatures can be provided upon request, like Class F.
Multi-Speed DC Fan Motor
Many applications require the maximum design conditions for only relatively short time periods, resulting in a waste of energy and consequently, a high running cost. To overcome this, Tingertech can be supplied with DC fan motor. As professional ec fan motor manufacturers, a wide range of fan motor speed combinations can be provided, based upon the fan motor synchronous speeds. By this method, power savings can be substantial, as well as generating much lower noise levels.
Thermal protection in the form of thermistors are all incorporated in any of our fan motors. Thermistor overloads must be used in conjunction with these fan motors.
High Temperature Applications
When continuous operation in higher ambients is essential, the fan motor can be wound with Class H insulation. The maximum continuous ambient temperature for Class H insulation is 80ºC. The maximum ambient temperature depends upon the load being applied to the motor and the temperature rise of the motor.
FAQ
FAQ:
1. Q: How we get a same motor as we need?
A: For your same motor, please share us:
a.Your motor image and nameplate;
b.Detailed size of your motor.
2. Q: Can you provide us sample, is it free or need to pay?
A: Free sample is always available, freight cost on customer's side.
3. Q: What's your payment term?
A: 30% deposit and 70% balance before shipping by LC,TT on FOB term.
4. Q: What kind of product you can provide? A: As a professional factory of hvac motor and centrifugal fan (housing fan), many different motor models and centrifugal duct fans are on our list: fan coil unit motor for central air conditioner, motor for split, cabinet, window, ceiling air conditioner, cooler motor, blower motor, fan motor, heat pump motor, universal fan motor, indoor fan motor, outdoor fan motor, condenser fan motor, PG motor, and other HVAC/R MOTOR; BLDC motor, EC motor, stepper motor, single and three phase motor; AC Centrifugal fan, EC centrifugal blower as well as other HVAC parts, which are on our service to help cusotmer purchase.
5. Q: Is there a MOQ for your motors? A: Yes. The MOQ is between 100-500pcs for different models after sample approval. And it's also okay for us to accept smaller lots for the initial order.
6. Q: Could you send me a price list? A: Most of our motor are not standard products, they are customized based on different requirements like voltage, power and shaft dia and length etc. Thus, it's really difficult for us to provide a price list. If you could share your detailed requirements and quantity, we'll be sure to offer a very competitive price.
