You asked: What is the torque of wiper motor?

thatoneguy. With the worm gear on the motor, sites selling them state anywhere from 30ft-lb to 50 ft-lb of torque at roughly 60-70 RPM.

What is the torque of a windshield wiper motor?

Gearmotor for windshield wipers MRT62-43

Gearmotor for windshield wipers MRT62 – 43 1 Speed 2 Speed
Max. Current (A) 12 12 / 15
No Load Speed (RPM) 30 30 / 45
Nominal Torque (RPM) 4 4
Starting Torque (Nm) 40 40 / 35

How do you calculate torque on a wiper motor?

= Angular velocity x 60 / (2 x 3.14) = 0.98 * 60 / (2 * 3.14) = 9.3 rpm = 10 rpm The required motor torque from calculation is above is 2.55 Nm and required motor speed is 10 rpm. This requirement is easily fulfilled by wiper motor as it can give 5 Nm torque at 65 rpm.

How powerful is a wiper motor?

At any rate an average wiper draws 5 amps, rising to 10 to 12 amps under heavy/stall load. Supposing the motor efficiency is 60% then the total power maxes out around 4 x 10 x 12 watts = 480 watts input and 0.6 x 480 watts output power .

How much power does a wiper motor need?

Wiper motors will probably not exceed 50 watts (4.2 amps at 12 volts). A 30 amp motor will require 360 watts and probably produce at least 250 watts of mechanical power. An engine cooling fan or cabin heating/cooling fan might approach that power level.

How much weight can a wiper motor lift?

I believe wiper motors generate about 12-13 ft/lbs of torque, so if you have a small spindle to use instead of a winch, a wiper motor may very well lift a 50lb load…slowly (Cap’n Jack is on to something with using a lighter door).

How long does a wiper motor last?

The wiper motor on a car is supposed to last a lifetime. Typically, this will not be the case due to the conditions that this part of a car is exposed to. The heat and moisture that a wiper motor is exposed to on a daily basis will eventually lead to you having to get it replaced.

Can you reverse a windshield wiper motor?

Yes you can reverse the motor, they are usually series field motors, so you need to swap either the field windings or the brushes round, but the mechanics may get stuck. The output of the gear reduction operates a linkage that moves the wipers back and forth. …

Does a wiper motor need a relay?

The washer systems associated with your windshield wiper control switch usually doesn’t need a relay. It wires direct from the control to the pump.

How many amps does a 12V wiper motor draw?

Neither draw more than 2.5 amps at 12 volts on full load. Mine normally takes about 2 amps and runs at around 8 volts.

How fast does a windscreen wiper motor turn?

Some wiper motors have variable speeds of up to 60 revolutions per minute (rpm). Other motors can support different windshield wiper blade angles from 40 degrees up to 110 degrees to maximize wipe performance.
